Description

Technical Field

[0001] The present invention relates to the technical field of earthquake early warning, and particularly to an earthquake early warning system and method based on entangled quantum. Background Art

[0002] Earthquake early warning refers to a technology that, under the condition of using a seismic observation network for earthquake monitoring, after an earthquake occurs, quickly determines the three earthquake elements and the earthquake source mechanism according to the observation records of seismic stations near the epicenter and seismological principles, predicts the ground motion parameters, and issues alarm information to areas where the destructive seismic waves have not arrived and the predicted ground motion parameters exceed the fortification standard. The purpose of earthquake early warning is to minimize casualties and reduce economic property losses after a destructive earthquake occurs.

[0003] In the current field of earthquake early warning, the following several traditional technical means are mainly relied on: seismic wave detection technology, strain monitoring and tilt measurement, satellite remote sensing and GPS technology, and geomagnetic field change monitoring. Among them, the seismic wave detection technology is limited, resulting in a very short early warning time when the epicenter distance is relatively close, and it cannot provide sufficient response time for the public. And in extreme cases, due to the extremely small time difference between the arrival of P waves and S waves, it is difficult for traditional seismic wave detection technology to effectively identify and issue early warnings. The main disadvantages of strain monitoring and tilt measurement are that they cannot provide real-time early warnings, and the installation and maintenance costs of the equipment are relatively high. Satellite remote sensing and GPS technology have extremely high requirements for real-time performance. Due to the limitations of data collection and transmission, real-time early warnings cannot be provided instantaneously after an earthquake occurs. In addition, weather conditions and atmospheric conditions may interfere with the accuracy of satellite and GPS signals. Geomagnetic field change monitoring is still in the experimental stage, and relevant signal analysis and models have not been established yet, so it has not been widely evaluated in actual earthquake early warning systems at present.

[0004] Therefore, there is an urgent need to propose an earthquake early warning system and method based on entangled quantum to solve the technical problem in the prior art that earthquake early warning technology is affected by factors such as time, range, and cost, resulting in the inability to perform real-time early warning. Summary of the Invention

Detailed implementation manners

[0018] The preferred embodiments of the present invention will be specifically described below with reference to the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present invention to explain the principles of the present invention, rather than to limit the scope of the present invention.

[0019] Quantum entanglement means that entangled quantum pairs refer to two or more particles whose quantum states become interdependent after interaction. Even if they are far apart, measuring one particle will instantaneously affect the state of the other particle. This phenomenon is called "quantum entanglement", which is a very strange phenomenon in quantum mechanics and cannot be explained by classical physics.

[0020] A quantum entanglement channel refers to a special connection formed between two or more quantum particles through the phenomenon of quantum entanglement, making their states interdependent. Even if they are far apart, measuring the state of one particle will immediately affect the state of the other particle. This non-local instant correlation is the core characteristic of quantum entanglement.

[0021] Quantum information is an emerging field that uses the principles of quantum mechanics for information processing and communication. It involves various coherent characteristics of quantum systems, such as quantum parallelism, quantum entanglement, and quantum no-cloning. Through these characteristics, calculations, encoding, and information transmission are carried out. The most basic unit of quantum information is the quantum bit (qubit), which is a quantum system with only two states. Different from classical bits, a quantum bit can be in a superposition state, that is, in the states of 0 and 1 simultaneously, which enables quantum computing to have the ability of parallel processing.

[0022] An entangled state is a special form of a quantum state. A quantum state is a basic concept in quantum mechanics that describes the state of a quantum system. Quantum states can be divided into pure states and mixed states. A pure state means that the system is in a definite quantum state, while a mixed state means that the system is in a probabilistic mixture of multiple quantum states. An entangled state is a special relationship between two or more quantum systems, such that the states of these systems cannot be independently described and must be considered as a whole.

[0023] Such as Figure 1As shown, a specific embodiment of the present invention discloses a seismic early warning system 100 based on entangled quantum, including a quantum sensor array module 101, a quantum communication node 101, and a surface control center 102; the quantum sensor array module 101 and the surface control center 102 transmit information through entangled quantum pairs; The quantum sensor array module 101 is configured to detect a seismic-prone area through a quantum sensor array to obtain sensing data, convert each physical quantity data in the sensing data into quantum information, and transmit it to the surface control center 101 through the corresponding quantum communication node; the sensing data includes different types of physical quantity data; each physical quantity data corresponds to the quantum communication node one by one; It should be understood that it can be applied to any seismic early warning device. Among them, the seismic early warning system based on entangled quantum can be a software system running on a terminal device. The terminal device can be a server, a tablet computer, an augmented reality (AR) / virtual reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), a mobile phone, and other terminal devices. The specific type of the terminal device is not limited in the embodiments of the present application.

[0024] Among them, the earthquake early warning system based on entangled quantum can include a quantum sensor array module 101, a quantum communication node 101, and a surface control center 102. The quantum sensor array module 101 and the surface control center 102 transmit information through entangled quantum pairs. The quantum sensor array module 101 can include a qubit array, and each sensor unit in the qubit array is equipped with an array composed of superconducting qubits, ion extraction, or quantum dots. These qubits are designed to sensitively capture minute physical changes underground, such as minute pressure fluctuations, etc. Each quantum sensor consists of a qubit change array and an environmental detection module, and is installed at key geological sensor locations such as underground fracture zones. It is entangled with the quantum communication node of the control center through entangled quantum pairs, and precursor earthquakes are monitored by real-time detecting changes in the underground environment and temperature. Traditional physical quantities can also be collected through MEMS (Micro-Electro-Mechanical Sensor System) technology. The sensing data can include different types of physical quantity data, such as crustal strain, temperature, pressure changes, etc. Then, these physical quantities can be converted into input signals of qubits through MEMS to ensure precise underground changes in the quantum state. Thus, the quantum sensor array can be installed in earthquake-prone areas (such as active fault zones) to detect earthquake-prone areas and form a large-scale monitoring network. Then, each physical quantity data in the sensing data can be converted into quantum information through MEMS and then transmitted to the surface control center 102 through the corresponding quantum communication node. Among them, each physical quantity data corresponds to a quantum communication node one by one. Ensure that the information of each monitoring point can be quickly and real-time collected at the surface control center 102.

[0025] The surface control center 102 is used to analyze the quantum information and issue an earthquake early warning when an earthquake signal is analyzed.

[0026] Among them, the surface control center 102 is responsible for receiving and analyzing the quantum information transmitted by the sensors, obtaining the data stream collected by the quantum sensor array module 101 according to the quantum information, and analyzing it in combination with intelligent algorithms to determine the analysis result. When the analysis result includes an analyzed earthquake signal, an earthquake early warning can be issued, and the early warning methods include but are not limited to alarm prompts and broadcast prompts, etc.

[0027] Compared with the prior art, the quantum sensor array provided in this embodiment, which is provided with entangled quantum pairs, can sensitively capture minute physical changes underground. By detecting earthquake-prone areas with the quantum sensor array, more accurate sensing data can be obtained. Each physical quantity data in the sensing data is also converted into corresponding quantum information, reducing data interference between information and improving transmission efficiency. The quantum information is transmitted to the surface control center through the quantum communication node corresponding to each physical quantity data. That is, information transmission through entangled quantum pairs can reduce the influence of distance and range on the transmission process, so that the sensing data of earthquake-prone areas can be detected in a timely manner even in a faraway place, thereby improving the accuracy of the early warning information obtained by the surface control center through analyzing the quantum information. Even in a faraway place, real-time early warning of earthquake-prone areas can be carried out.

[0028] In some embodiments of the present invention, as Figure 2 shown, the system 100 further includes a quantum pair generation module 103; The quantum pair generation module 103 is used to generate entangled quantum pairs through an entangled quantum pair emitter; each pair of photons on the entangled quantum pairs maintains an entangled state, one of the photons is guided to the quantum sensor of the quantum sensor array module underground, and the other photon is transmitted to the surface control center 102.

[0029] Among them, a high-performance entangled quantum pair emitter can be used, and a nonlinear crystal (such as β-boric acid crystal) is selected to generate entangled pairs. Each pair of photons maintains an entangled state, one of the photons is in the underground sensor (i.e., the quantum sensor) of the quantum sensor array module, and the other photon is emitted to the surface control center. Specifically, the entangled quantum pairs can be generated by utilizing the nonlinear optical effect. When a high-energy laser beam irradiates a nonlinear crystal (such as β-barium borate crystal), a special quantum process will occur, namely spontaneous parametric down-conversion (SPDC). In this process, a high-energy photon will split into two low-energy photons in the nonlinear crystal, and these two photons form an entangled quantum pair. This entanglement is manifested as a special correlation between certain quantum properties (such as polarization, momentum, etc.) of the two photons. No matter how far apart they are, the measurement result of one photon will instantaneously affect the state of the other photon, reflecting the non-locality of quantum entanglement.

[0030] Laser source part: A laser generator with high stability and high output energy is adopted. The laser beam output by it is collimated and focused through a series of optical lenses to ensure that the laser can accurately irradiate a specific area of the nonlinear crystal. The laser generator needs to be installed on a stable optical platform to reduce the influence of external vibration on the laser output. At the same time, a temperature control system is equipped to ensure that the laser generator works in a constant temperature environment, thereby improving the stability of the laser output.

[0031] Nonlinear crystal part: The β-barium borate crystal is placed in a carefully designed crystal holder, which can accurately adjust the position and angle of the crystal to optimize the spontaneous parametric down-conversion process. A temperature adjustment device is set around the crystal to keep the crystal at the optimal working temperature because the performance of the crystal is very sensitive to temperature. In addition, optical filters are installed at both the incident and exit ends of the crystal to filter out unwanted light components and only allow the generated entangled quantum pairs to pass through smoothly.

[0032] Photon separation and transmission part: After the generated entangled quantum pairs exit from the nonlinear crystal, they are separated by a set of optical beam splitters. One photon is guided to the underground quantum sensor, and the other photon is transmitted to the communication node on the ground surface. On the transmission path, low-loss optical fibers are arranged, and the fibers are surrounded by buffer materials and shielding layers to reduce the interference of the external environment on photon transmission and ensure that the photons can reach the destination stably.

[0033] It should be noted that: In order to ensure the stability of the entangled state during long-distance transmission without being destroyed, a method combining quantum relay and quantum error correction code needs to be adopted.

[0034] Quantum technology can be used for the processing of quantum relay nodes. In some embodiments of the present invention, the quantum sensor array module 101 is also used to periodically deploy quantum relay nodes on the transmission path for transmitting quantum information to the ground control center 102 through the quantum communication node, and establish entangled connections between adjacent quantum relay nodes to extend the transmission distance of the entangled state of the entangled quantum pairs.

[0035] Among them, the role of quantum technology (quantum relay): Since photons will have certain absorption and scattering in transmission media such as optical fibers, the entangled state decays rapidly during long-distance transmission. The quantum relay connects short-distance strong entanglements through entanglement swapping to form long-distance entanglement, greatly extending the transmission distance of the entangled state and ensuring the reliable transmission of quantum information over long distances.

[0036] Quantum error correction code can be used for quantum coding processing. In some embodiments of the present invention, the quantum sensor array module also includes a quantum error correction coding sub-module; The quantum error correction coding sub-module is used to detect and correct the quantum information received by each quantum relay node according to the preset error correction code rules, so that the surface control center 102 receives the correct quantum information.

[0037] Among them, the role of the error correction code: The quantum system is very fragile and is easily interfered by the external environment, resulting in errors in the quantum state. The error correction code can detect these errors and correct them, thus ensuring the integrity and accuracy of the entangled state during transmission. Even if some small errors occur during transmission, they can be repaired in time through the error correction code, enabling the surface control center to receive the correct quantum information.

[0038] In a specific embodiment of the present invention, the specific implementation process of the method combining quantum relay and quantum error correction code is as follows: After the entangled photon pairs are generated, use a classical computer program to operate the quantum gates, and encode the quantum state to be transmitted according to specific error correction code rules (such as surface code, Reed-Solomon code, etc.). For example, when using surface code encoding, map a logical qubit to multiple physical qubits to construct a stable encoded state. This step is realized by means of the error correction code encoding software running in the quantum control computer to perform control operations.

[0039] On the long-distance transmission path from the underground sensor to the surface control center, quantum relay nodes are periodically deployed. Each relay node includes an entanglement source, a quantum storage device, and a quantum operation unit.

[0040] First, adjacent quantum relay nodes each generate entangled photon pairs through the entanglement source, and retain one photon in the local quantum storage device (such as atomic ensemble, quantum dot, etc.), and send the other photon to the adjacent node.

[0041] Then, use entanglement swapping technology to establish an entanglement connection between adjacent relay nodes, and expand the initial short-distance entanglement into long-distance entanglement. For example, when relay nodes A and B establish an entanglement correlation through entanglement swapping, then perform entanglement swapping between B and the next relay node C to gradually realize the connection of long-distance quantum entanglement.

[0042] Each quantum relay node and the surface control center are provided with an error detection unit. These modules continuously monitor the received quantum state, and judge whether an error occurs and the type and location of the error by measuring the auxiliary qubits and according to the error correction code rules.

[0043] If an error is detected, the quantum operation unit of the relay node or the surface control center will perform corresponding quantum gate operations according to the error information to correct the error. For example, for a bit flip error, a single-bit quantum gate (such as the X gate) can be used for correction; for a phase flip error, the Z gate can be used for correction.

[0044] A feedback control system is established, which continuously collects data during the error detection and correction process, and statistically analyzes the frequency and type of errors. According to the feedback data, the working parameters of the quantum relay node are dynamically adjusted, such as the output power of the entanglement source, the time parameters of quantum storage, etc., to optimize the entanglement transmission process, further reduce the error rate, and ensure the long-term stability of the entangled state.

[0045] Among them, as Figure 3 shown, the quantum sensor array module 101 may further include a quantum error correction coding sub-module 1011, a quantum relay node 1012, and a feedback control system 1013. The quantum error correction coding sub-module 1011 may include a quantum control computer 111 and a quantum gate operation device 112.

[0046] Quantum control computer 111: It is used to run the program of the error correction code encoding algorithm and control the quantum gate operation to encode the quantum state. It includes a high-speed processor and a large-capacity memory, and can quickly execute complex quantum algorithms.

[0047] Quantum gate operation device 112: It is composed of a microwave generator, a laser modulator, etc. According to the instructions of the quantum control computer, various quantum gate operations are applied to the quantum bits to achieve error correction code encoding.

[0048] The quantum relay node 1012 may include an entanglement source 121, a quantum storage device 122, a quantum operation unit 123, and an error detection unit 124.

[0049] Entanglement source 121: It can be an entangled photon pair generator based on a nonlinear optical crystal (such as the above-mentioned β-barium borate crystal), which can stably generate high-quality entangled photon pairs.

[0050] Quantum storage device 122: Such as an atomic ensemble, a quantum dot, or a superconducting qubit, etc., which is used to temporarily store quantum bits and provide sufficient operation time for entanglement swapping and error correction.

[0051] Quantum operation unit 123: It includes a series of quantum gates (such as single-bit gates and multi-bit gates), which are used to perform entanglement swapping and error correction operations. It can be driven by microwave pulses, laser pulses, etc.

[0052] Error detection unit 124: It is composed of a single-photon detector, a quantum state measurement device, and a classical data processing circuit. The single-photon detector is used to detect photon signals, the quantum state measurement device obtains error information by measuring the auxiliary quantum bits, and the classical data processing circuit analyzes and judges the measurement data to determine the error situation.

[0053] The feedback control system 1013 may include a data acquisition unit 131, a data analysis and decision-making unit 132, and a parameter adjustment unit 133.

[0054] Data acquisition unit 131: Collect error detection data of each node, including information such as the time, location, and type of error occurrence.

[0055] Data analysis and decision-making unit 132: Perform statistical analysis on the collected data and generate instructions for adjusting parameters according to preset optimization rules.

[0056] Parameter adjustment unit 133: Receive instructions from the data analysis and decision-making unit and perform real-time adjustment on the working parameters of the quantum relay node, such as changing the drive current of the entanglement source, the control pulse of the quantum storage, etc.

[0057] In some embodiments of the present invention, the quantum sensor array module 101 is also used to perform communication initialization with the surface control center 102 through quantum scheduling technology, determine the quantum entanglement channels of each quantum communication node, and transmit the corresponding quantum information to the surface control center 102 through the quantum entanglement channels.

[0058] In a specific embodiment of the present invention, the quantum scheduling (QKD) technology is mainly used to establish an initial connection between the surface control center and the underground quantum sensors. After the underground quantum sensors are deployed and ready to collect data, they perform communication initialization with the surface control center through QKD technology, so as to determine the quantum entanglement channels of each quantum communication node, and then the corresponding quantum information can be transmitted to the surface control center through the quantum entanglement channels, ensuring the rapid transmission of data and consuming traditional electromagnetic signals, thereby avoiding transmission delays caused by environmental interference.

[0059] In some embodiments of the present invention, the quantum sensor array module 101 is also used to generate a shared random quantum key by using quantum entanglement pairs and the quantum key distribution protocol, and encrypt and transmit quantum information through the random quantum key.

[0060] In a specific embodiment of the present invention, during the initial connection process, the two parties negotiate a shared random quantum key through the quantum key distribution protocol for subsequent encrypted communication. Specifically: Key generation: The surface control center and the underground quantum sensors use quantum entanglement pairs and the quantum key distribution protocol (such as the BB84 protocol) on the quantum sensor array module to generate a shared random quantum key. In this protocol, the two communicating parties randomly measure different quantum states (such as polarization states) of entangled photons, and then publicly disclose a part of the measurement basis information through the classical communication channel, and retain the data at the same positions where the measurement basis selections are the same as the initial key.

[0061] Key negotiation: The two parties compare the measurement results, select the consistent measurement values to form an initial key. Then, error - correcting code technology is used to correct the errors in the initial key, removing the inconsistent information caused by measurement errors or external interference. Next, privacy amplification technology is used to process the error - corrected key to eliminate the part of the information that may be obtained by eavesdroppers, and finally a secure shared quantum key is generated.

[0062] Data encryption: After the underground sensors convert the collected data into quantum - state signals, the generated quantum key is used to encrypt these data. The one - time pad (OTP) encryption method is adopted, and the quantum - state signal and the quantum key are subjected to a bit - by - bit exclusive - OR operation to obtain the encrypted quantum information. This encryption method has absolute security because the quantum key is used once and randomly generated. Any attempt to steal the key or crack the encrypted information will destroy the quantum state and thus be detected by both communicating parties.

[0063] Security monitoring: During the communication process, the security of the quantum channel is continuously monitored. By regularly exchanging additional test bits to check for eavesdropping. If signs of eavesdropping are found, the communication is immediately interrupted and a new quantum key is regenerated to ensure the security of the communication.

[0064] In some embodiments of the present invention, each physical quantity data corresponds to a quantum - bit state; the quantum sensor array module 101 further includes a quantum control sub - module; The quantum control sub - module is further configured to perform data conversion on each physical quantity data respectively to obtain the corresponding quantum - bit state; according to the different characteristics of each physical quantity data, determine the change situation of each quantum - bit state to obtain the quantum information of each physical quantity data.

[0065] Among them, the quantum control sub - module is further configured to convert multiple physical quantity data into electrical signals, and then send the electrical signals to the quantum modulator, and the quantum modulator converts the electrical signals into the quantum - bit states corresponding to each physical quantity data.

[0066] In a specific embodiment of the present invention, the quantum sensor array module may further include a quantum control sub-module. The specific method for controlling the state of qubits is as follows: when the sensor collects abnormal physical quantity data (such as changes in strain, temperature, etc.) of the underground environment, the quantum control sub-module in the sensor controls the state of the qubits. Among them, each physical quantity data in the sensing data corresponds to a qubit state. The quantum control sub-module is composed of a series of quantum logic gates, such as Pauli gates, Hadamard gates, etc. After different characteristics of the collected physical signals are obtained, the physical signals can be converted into electrical signals, and then the electrical signals are sent to the quantum modulator. The quantum modulator of the quantum control sub-module will select appropriate quantum logic gates to operate on the qubits, that is, determine that each physical quantity data corresponds to a qubit state. For example, if an increase in crustal strain is detected, the quantum control sub-module will apply a specific Pauli-X gate operation corresponding to the crustal strain to flip the state of the qubit of the crustal strain from |0> to |1>. This state change will be instantaneously transmitted to the corresponding entangled photons at the surface control center through the quantum entanglement of quantum information, thereby realizing the real-time transmission of underground detection signals.

[0067] Multiple choices are available. Since each physical quantity data corresponds to a qubit state, and similarly, multiple quantum entanglement channels correspond one-to-one with multiple physical quantity data, the quantum sensor array module 101 can also synchronously process multiple physical quantity data, so that the quantum information of each physical quantity data can be transmitted to the surface control center through the corresponding quantum entanglement channel, avoiding data stream conflicts. Each physical quantity is processed through an independent channel and mapped to the corresponding qubit state, ensuring that quantum communication is not interfered by external signals. Among them, the quantum sensor transmits quantum information to the communication node in nanosecond-level precision, enabling changes in underground physical quantities to be instantaneously reflected in the surface control system. This rapid transmission greatly improves the timeliness of early warning.

[0068] In some embodiments of the present invention, the surface control center 102 is further configured to convert the quantum information according to a random quantum key to obtain sensing data, detect the sensing data according to a preset early warning model to obtain a prediction result, and issue an early warning according to the early warning level in the prediction result.

[0069] In a specific embodiment of the present invention, after receiving quantum information, the ground control center can convert the quantum information according to a random quantum key to obtain sensing data, and then can detect the sensing data through a preset early warning model to obtain a prediction result. Among them, the preset early warning model can be a model for earthquake early warning constructed by a high-performance computing cluster and an AI algorithm. The control center is equipped with a multi-core processor and a workpiece computing system, and develops a specific convolutional neural network (CNN) and long short-term memory network (LSTM) for analyzing sensor data streams. Especially when identifying non-linear and complex earthquake precursor signals, it has high stability and accuracy. Through data stream processing and big data analysis techniques, it can process data from a large number of sensors in real time. During the analysis process, the system uses machine learning and deep learning models, combined with earthquake historical data for pattern recognition and prediction. Algorithm optimization and adaptive learning: The AI platform can not only detect earthquake signals, but also self-learn and optimize the prediction model. The system combines the data collected by actual sensors to adjust and optimize the parameters of the signal processing algorithm in real time, so that the early warning system maintains a high preset. Any small correction deviation can be fed back to ensure the occurrence of a no-false-alarm mechanism. After the new data captured by the earthquake precursor signal is labeled, the system can adjust the parameters in real time according to the new data to improve the accuracy of earthquake early warning.

[0070] Among them, different early warning levels can also be set: The early warning level incorporates multi-level trigger early warning schemes, from primary early warning (detecting minor anomalies) to advanced early warning (an imminent large-scale earthquake). Different early warning levels will automatically trigger the corresponding alarm release. Combining risk analysis and emergency response plans, the early warning signal will be directly sent to the notification systems in key areas such as public transportation, hospitals, and schools. Thus, the early warning level can be determined according to the prediction result, and then early warning can be carried out according to the early warning level.

[0071] In the embodiments of the present invention, through quantum entanglement communication, the moment a quantum sensor detects a signal, it can be synchronized to the surface nodes, greatly solving the problem of signal propagation delay in traditional methods. This technology reduces the response time of the early warning system from the order of seconds to the order of dozens, greatly improving the timeliness of emergency response. High-sensitivity response of quantum states to minute changes: The system's detection ability for crustal changes and pressure fluctuations has increased by more than several times. Derived from traditional mechanical sensors, quantum sensors can respond to minute changes in physical quantities and can accurately detect even in complex underground environments, enhancing the ability to capture pre-earthquake signals. Quantum signal transmission is not affected by electromagnetic interference, which enables the system to operate stably in any environment. Even when the underground electromagnetic field is continuously increasing, quantum signal transmission can still maintain stable signal transmission. Quantum signal transmission is not affected by electromagnetic interference, which enables the system to operate stably in any environment. Even when the underground electromagnetic field is continuously increasing, quantum signal transmission can still maintain stable signal transmission.
