Description

Technical Field

[0001] This application relates to the field of optical systems, and in particular to an optoelectronic hybrid integrated high-entropy dual parallel quantum random number generator. Background Technology

[0002] In secure communication and encryption technologies, the generation of truly random numbers is crucial for ensuring system security and efficiency. With the rapid development of quantum technology, quantum random number generators are gradually moving from the laboratory to practical applications. The integration, scalability, and continuous improvement of random number generation rates of quantum random number generators have become urgent requirements for meeting the rapid development of information networks. Summary of the Invention

[0003] The purpose of this application is to provide a photoelectric hybrid integrated high-entropy dual parallel quantum random number generator, which can improve the true random entropy content, integration, and generation efficiency of the random number generator.

[0004] To achieve the above objectives, this application provides the following solution: In a first aspect, this application provides a photoelectric hybrid integrated high-entropy dual-parallel quantum random number generator, which includes a photoelectric hybrid integrated entropy source module, a multi-quantum frequency mode parallel extraction circuit, and a hardware real-time random number post-processing module; wherein... The optoelectronic hybrid integrated entropy source module is used to perform quantum optical field beat detection using a silicon-based optoelectronic chip to generate an optoelectronic signal originating from the fluctuations of two orthogonal components of a quantum state; the optoelectronic signal is then sent to the multi-quantum frequency mode parallel extraction circuit. The parallel extraction circuit for multiple quantum frequency modes is used to receive the photoelectric signal; acquire multiple sub-signals based on the photoelectric signal; and extract multiple high-frequency sideband quantum modes that are mutually independent in the frequency domain from the multiple sub-signals in parallel. The hardware real-time random number post-processing module is used to perform parallel hashing post-processing on the original random numbers derived from multiple high-frequency sideband quantum modes, and finally output multiple parallel or synthesized true random numbers.

[0005] Secondly, this application provides a method for generating high-entropy dual-parallel quantum random numbers using a hybrid optoelectronic approach, the method comprising: A silicon-based optoelectronic chip is used for quantum optical field beat detection to generate photoelectric signals originating from the fluctuations of two orthogonal components of a quantum state; Based on the photoelectric signal, multiple sub-signals are acquired, and multiple high-frequency sideband modes are extracted in parallel from the multiple sub-signals; The original random numbers originating from multiple high-frequency sideband quantum modes are subjected to parallel hashing post-processing, and finally output as parallel multi-path or synthesized true random numbers.

[0006] According to the specific embodiments provided in this application, the following technical effects are disclosed: In the solution provided in this application, quantum random fluctuation signals of orthogonal components of the optical field are obtained based on beat detection.

Figure 3 This is a schematic diagram of the structure of a second type of optoelectronic hybrid integrated high-entropy dual parallel quantum random number generator in one embodiment of this application. Detailed Implementation

[0009] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0010] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0011] In one embodiment of this application, see Figure 1 A hybrid optoelectronic high-entropy dual-parallel quantum random number generator is provided, comprising: a hybrid optoelectronic entropy source module, a multi-quantum frequency mode parallel extraction circuit, and a hardware real-time random number post-processing module; wherein, The optoelectronic hybrid integrated entropy source module is used to perform quantum optical field beat detection using silicon-based optoelectronic chips, generating optoelectronic signals originating from the fluctuations of two orthogonal components of a quantum state; the optoelectronic signals are then sent to a multi-quantum frequency mode parallel extraction circuit. A parallel extraction circuit for multiple quantum frequency modes is used to receive photoelectric signals; multiple sub-signals are acquired based on the photoelectric signals, and multiple high-frequency sideband quantum modes that are independent of each other in the frequency domain are extracted in parallel from the multiple sub-signals; The hardware real-time random number post-processing module is used to perform parallel hashing post-processing on the original random numbers derived from multiple high-frequency sideband quantum modes, and finally output multiple parallel or synthesized true random numbers.

[0012] The photoelectric signal is generated by beat detection of chaotic laser or vacuum field; the specific generation method is described in subsequent embodiments. The fluctuations of the orthogonal components of the high-frequency quantum mode of chaotic laser are nonlinear amplifications of vacuum quantum fluctuations. They are high-entropy quantum signals originating from the intrinsic randomness of quantum mechanics, making the quantum random entropy content of the system much higher than the classical noise entropy content of most previous vacuum-state-based schemes in this field, thereby improving the true random entropy content.

[0013] High-frequency sideband quantum mode: refers to the quantum fluctuation signal within a certain bandwidth with a specific radio frequency as the analysis frequency, extracted from a broadband optoelectronic signal based on downmixing when performing balanced zero-beat or difference-beat detection on the orthogonal components of a continuous variable quantum state. It is the definition of a practically operable quantum state or quantum mode in continuous variable quantum communication.

[0014] High frequency refers to frequencies typically higher than a few kHz or tens of kHz. Since laser systems are inevitably subject to classical noise disturbances, the broadband continuous variable quantum state orthogonal component fluctuation photoelectric signal obtained by balanced zero-beat or differential beat detection can be obtained by downmixing to extract high-frequency sideband modes far from the low-frequency classical noise band, thus resisting classical noise interference and obtaining pure quantum fluctuation signals.

[0015] High-frequency sideband modes can provide broadband, flat optical random entropy sources with stable quantum entropy content, which are suitable for ultra-high-speed random number generation and can be seamlessly integrated with optical communication systems.

[0016] The hardware real-time random number post-processing module is based on FPGA (Field-Programmable Gate Array) to realize parallel real-time random number post-processing and true random number aggregation output.

[0017] Furthermore, the optoelectronic hybrid integrated entropy source module, the multi-quantum frequency mode parallel extraction circuit, and the hardware real-time random number post-processing module are integrated and packaged together.

[0018] The aforementioned integration can reduce system footprint, improve device stability, and adapt to the rapidly developing quantum communication system, providing support for the real-time stable generation of high-bandwidth, low-latency random numbers.

[0019] In the solution provided in this application, photoelectric signals are obtained based on laser field beat detection. The randomness of the photoelectric signals stems from fundamental properties of quantum mechanics: the generation, arrival time, polarization state, and phase of photons all follow a probability distribution and cannot be precisely predicted, providing a good foundation for generating random numbers. Furthermore, by processing the photoelectric signals, multiple high-frequency sideband modes can be extracted in parallel, and each high-frequency sideband mode can independently generate random numbers. This improves the extraction efficiency of the photoelectric quantum entropy source, the integration and scalability of the photoelectric quantum random number generator, and exponentially increases the generation efficiency of quantum random numbers.

[0020] Random number generators are widely used in various fields such as encryption algorithms, statistical analysis, and simulation. These applications require high-quality and high-speed random numbers, especially in scenarios such as high-performance computing, big data processing, and real-time information network systems. Traditional true random number generation methods often cannot meet the high requirements for generation speed and scalability. In particular, high-speed random number generation is crucial for key security in cryptography; and in large-scale simulation and data analysis, rapidly generating a large number of random numbers is a necessary condition for improving efficiency and accuracy. The embodiments of this application can generate quantum true random numbers in real time and quickly through the above-mentioned dual parallel scheme, thereby improving the applicability of this application scenario. The implementation of this application not only provides a new approach to quantum random number generation, but also has broad application prospects in quantum communication, network security, random encryption, and big data protection.

[0021] In one embodiment, the optoelectronic hybrid integrated entropy source module includes: a laser module and a silicon-based optoelectronic chip; The laser module contains a laser chip used to emit background laser and chaotic laser to the silicon-based optoelectronic chip; The laser module includes a laser chip, a monitoring module, and a control module, used to monitor and control the emission of background laser and chaotic laser to the silicon-based optoelectronic chip; The silicon-based optoelectronic chip uses a 90-degree optical mixer to receive background laser and chaotic laser, performs optical interference between the background laser and chaotic laser, and then obtains a pair of orthogonal components of the optical quantum electrical signal originating from the high-frequency quantum mode of the chaotic optical field based on balanced detection.

[0022] Specifically, the laser module can include two types of laser chips: LD laser chips and chaotic laser chips.

[0023] The LD laser chip is used to emit background laser light, which is coupled into the silicon-based optoelectronic chip through the end face, and then enters the local oscillator port of the 90-degree optical mixer through a single-mode waveguide.

[0024] The chaotic laser chip emits chaotic laser light, which is coupled into the silicon-based optoelectronic chip through the end face, and then enters the signal port of the 90-degree optical mixer through a single-mode waveguide. The fluctuation of the chaotic state component is used as the source of high entropy. When the signal port of the 90-degree optical mixer does not inject chaotic laser light, the fluctuation of the quantum vacuum state component is used as the source of entropy.

[0025] Silicon-based optoelectronic chips include end-face couplers for achieving end-face coupling. For example, flat end faces can be directly connected to make the end face parallel to and close to the laser cleavage surface, or lens coupling can be used. The embodiments of this application do not limit this.

[0026] In one embodiment, the chaotic laser chip is a Keysight DFB laser chip; the background laser chip is a 1550nm high-power semiconductor laser chip; the field-programmable gate array is a Xilinx Kintex-7 XC7K325T; the analog-to-digital converter is an ADS42LB69; and the multi-quantum frequency mode parallel extraction circuit is implemented using Rogers 4350 material with good high-frequency performance.

[0027] Specific silicon-based optoelectronic chips may include: end-face couplers, unbalanced beam splitters, 90-degree optical mixers, optical attenuators, and photodetectors.

[0028] An end-face coupler is used to couple the laser generated by a laser chip into a silicon-based optoelectronic chip.

[0029] An unbalanced beam splitter is used to distribute the optical power of the coupled local oscillator laser at a ratio of 95% and 5%, with 5% of the optical power used to detect the coupling status and the other 95% of the optical power transmitted through a single-mode waveguide to the local oscillator port of a 90-degree optical mixer.

[0030] A 90-degree optical mixer is used to receive background laser and chaotic laser, interfere the background laser and chaotic laser, and then convert them into electrical signals by a photodetector.

[0031] An optical attenuator is used to adjust the amount of light power entering the photodetector.

[0032] Chaotic lasers refer to broadband, non-periodic lasers. When mixed with a background laser, mode selection is performed based on 90-degree optical mixer interference, and then the orthogonal components are balanced and detected to obtain photoelectric signals originating from the quantum fluctuations of the two orthogonal components of the chaotic field.

[0033] The fluctuations of the orthogonal components of the high-frequency quantum modes in chaotic lasers are a nonlinear amplification of vacuum quantum fluctuations, resulting in a higher quantum random entropy content compared to classical noise entropy content. This is a high-entropy quantum signal originating from intrinsic quantum randomness. Correspondingly, the multiple high-frequency sideband modes extracted by mixing and filtering the photoelectric quantum signals based on the quantum fluctuations of the two orthogonal components of the chaotic field also possess quantum randomness and can be used as quantum noise simulation signals.

[0034] In one embodiment of this application, the laser module further includes a monitoring module and a control module.

[0035] The monitoring module monitors the laser chip temperature and output power in real time based on the microcontroller unit (MCU); the control module implements temperature control and constant current drive based on the microcontroller unit.

[0036] Temperature monitoring involves collecting the temperature of the laser chip using a temperature sensor; output power monitoring involves collecting the current value generated by the 5% output terminal of the unbalanced beam splitter entering the photodetector, and combining this with the photodetector's responsivity and the beam splitting ratio of the unbalanced beam splitter to monitor the laser's output power.

[0037] The control module uses an MCU to implement temperature control and constant current drive.

[0038] Temperature control dynamically adjusts the drive voltage of the MCU output to the TEC (Thermoelectric Cooler) based on the acquired temperature value, thereby precisely stabilizing the temperature of the laser chip at the set value. Constant current drive circuit dynamically adjusts the drive voltage of the MCU output to the digital power chip with negative feedback structure based on the acquired current value generated by the 5% output terminal of the unbalanced beam splitter entering the photodetector, thereby generating a constant current and stabilizing the output optical power of the laser chip at the set value.

[0039] In one embodiment, the multi-quantum frequency mode parallel extraction circuit includes: Radio frequency amplifier circuits, power dividers, mixers, signal generators, and low-pass filters; Radio frequency amplifier circuits are used to amplify optical quantum electrical signals to obtain macroscopic signals; A power divider is used to distribute an amplified signal into multiple sub-signals. A mixer is used to mix multiple sub-signals with a high-frequency radio frequency reference signal generated by a signal generator. The low-pass filter performs low-pass filtering on the above mixed signal and, in combination with the mixer, achieves down-mixing, which is used to extract the high-frequency quantum sideband mode with the corresponding high-frequency radio frequency reference signal as the center frequency from the multi-channel optical quantum electrical signal.

[0040] For the specific circuit structure, please refer to Figure 2 As shown in the figure, the laser module includes: 1. MCU; 2. Temperature control circuit; 3. Constant current drive circuit; 4. LD laser chip; 5. Chaotic laser chip; The silicon-based optoelectronic chip includes: 6. End-face coupler; 7. Unbalanced beam splitter; 8. Photodetector; 9. Optical mixer; 10. Optical attenuator; 11. Balanced photodetector; The parallel extraction circuit includes: 12. RF amplifier circuit; 13. Power divider; 14. Signal generator; 15. Mixer; 16. Low-pass filter; The post-processing section includes: 17. Analog-to-digital converter; 18. Field-programmable gate array.

[0041] In one embodiment, the hardware real-time random number post-processing module includes a data acquisition module, a true random number extraction module, and a data output module; wherein... The data acquisition module is used to generate the original random bit data stream corresponding to the high-frequency sideband mode; The randomness extraction module is used to extract the quantum random number sequence from the original random data stream; The data output module is used to output multiple and merge one true random number based on the quantum random number sequence.

[0042] The above post-processing module is implemented based on a field-programmable gate array (FPGA).

[0043] The data acquisition module uses a high-speed analog-to-digital converter to digitize the high-frequency sideband mode at a fixed sampling rate, generating a raw random data stream; the randomness extraction module performs a hash operation on the raw data stream based on the Toplitz matrix, thereby extracting a statistically uniform quantum random number sequence to improve system security. The data output module outputs the final quantum random number sequence processed by the serial peripheral interface to the external device at a constant rate.

[0044] In this embodiment, multiple high-frequency sideband modes can be generated in parallel, and correspondingly, they can be processed in a pipeline manner, as described in the following embodiments. After extracting a quantum random number sequence for each high-frequency sideband mode, random numbers can be obtained from the quantum random number sequence in parallel.

[0045] In the above system, the optoelectronic hybrid integrated entropy source module adopts hybrid integrated packaging, integrating optical components and electronic control circuits on the same platform; the laser module and the silicon-based optoelectronic chip use end-face coupling technology for packaging; the laser module uses a ceramic substrate as the base material for the electronic circuit; the silicon-based optoelectronic chip adopts an SOI silicon-based structure; the multi-quantum frequency mode parallel extraction circuit uses a printed circuit board (PCB) for wiring; the optoelectronic hybrid integrated entropy source module and the multi-quantum frequency mode parallel extraction circuit are connected by gold wire bonding technology.

[0046] This invention utilizes optoelectronic hybrid integration technology to construct a quantum random number generator, which improves the system's long-term stability and resistance to environmental interference. The aforementioned chip-level packaging significantly reduces system size and power consumption, promoting the miniaturization, cost reduction, and practical application of quantum random number generators.

[0047] Specifically, the dual parallelism is reflected in two aspects: the extraction of the biorthogonal components of the continuous variable quantum state and the parallel extraction of multiple high-frequency sideband quantum modes of each component.

[0048] In one embodiment, the aforementioned 90-degree optical mixer is based on a multi-mode interference (MMI) structure to achieve heterodyne detection based on vacuum fluctuations or chaotic laser injection, such that the generated optical quantum electrical signal includes two orthogonal signals and two in-phase signals.

[0049] When chaotic laser is not injected into the signal port of the 90-degree optical mixer, a vacuum is maintained, realizing the generation of an entropy source based on vacuum fluctuations. When chaotic laser is injected into the signal port, a high-entropy entropy source is generated.

[0050] MMIs rely on the principle of multimode interference self-imaging. When light propagates in a multimode waveguide, different modes superimpose, forming a fixed amplitude and phase distribution at the output surface. In one embodiment, for a standard 4×4 MMI 90-degree mixer: The input ports for the two signals are not arbitrary. When the two input ports are 1-2, 1-3, 2-4, or 3-4 respectively, the requirement for 90-degree mixing can be met. Using ports 1-3 as the two input ports of the optical mixer, the input local oscillator light and signal light will be uniformly coupled to the four output ports, and the outputs will have a fixed phase difference. Output 1: 0° Output 2: 90° Output 3: 270° (= -90°) Output 4: 180° This is determined by the geometry of the MMI structure itself, and no additional phase shifter is needed.

[0051] Input methods for chaotic laser S and local laser LO: Chaotic laser S is input from the signal input port of MMI, and local laser LO is input from the local oscillator input port of MMI.

[0052] After entering the MMI, S and LO propagate simultaneously and interfere with each other within the multimode waveguide.

[0053] The process of forming I and Q quadrature components at the output terminal: In each of the four output waveguides, the output = the component of S + the component of LO; and it inherently possesses the phase relationship of the MMI. First output (I+): S+L, with the first path as the reference phase 0°, forms the I positive phase branch.

[0054] Second output (Q+): S+jL, with a 90° phase difference from the first path, forms the Q positive phase branch.

[0055] Third output (Q-): S-jL is 270° (-90°) out of phase with the first path and is out of phase with Q+.

[0056] Fourth output (I-) SL is 180° out of phase with the first path and is out of phase with I+.

[0057] The above generates in-phase and quadrature signals. Thus, this application realizes multi-path parallel quantum entropy source extraction of two components. Combined with heterodyne detection, synchronous detection of the two components can be achieved. Furthermore, by performing multi-band parallel processing on each component, multiple entropy source extractions can be realized, significantly increasing the random number generation rate.

[0058] In one embodiment, the data acquisition module converts analog signals into raw random data streams using an analog-to-digital converter.

[0059] In one embodiment, the data acquisition module automatically moves the raw random data stream output by the analog-to-digital converter to a memory buffer by setting a direct memory access controller, thereby enabling hardware-level parallel pipelined data acquisition and subsequent processing. Data acquired through the memory buffer can directly execute subsequent data processing procedures without waiting for all data in the raw random data stream to be read, allowing data generation and extraction to be performed in parallel, achieving pipelined processing.

[0060] In one embodiment, in the randomness extraction module, the field-programmable gate array performs hash extraction on the original random data stream based on the Toplitz matrix to obtain a quantum random number sequence; Corresponding to the above embodiments, in one embodiment of the present invention, see...
