At present, the online circulation and transmission of electronic archives mainly rely on traditional cryptographic schemes, such as RSA, AES and other encryption algorithms, and realize data transmission through security protocols such as SSL / TLS. These schemes usually use public key infrastructure (PKI) for key distribution, and use a combination of symmetric encryption and asymmetric encryption to protect data security. At the transmission level, existing technologies mainly transmit encrypted archive data through optical fiber communication networks or wireless communication networks, supplemented by digital signatures, access control and other technical means to ensure the security of the transmission process.

DETAILED DESCRIPTION

[0019] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Example 1, reference Figure 1 , which is an embodiment of the present invention, provides an online circulation and transmission method of electronic archives based on quantum technology.

[0022] The present application provides an effective solution to the above-mentioned problems. Next, multiple embodiments will be combined to explain in detail how to implement the online circulation and transmission method of electronic archives based on quantum technology.

[0023] Figure 1 The overall flow chart of the online circulation and transmission method of electronic archives based on quantum technology is shown, including: S1: Obtain the electronic file to be transmitted and generate the quantum key for encrypted transmission through quantum key distribution technology.

[0024] S1.1: Receive the electronic file to be transmitted, and store the electronic file in a preset quantum memory.

[0025] It should be noted that electronic files can be official documents of government departments, business contracts of enterprises, patient medical records of medical institutions and other digital files that require high security protection. These files usually contain sensitive information, and if traditional storage methods are used, they are vulnerable to hacker attacks or data leaks. Quantum memory is a new type of storage device that stores information based on quantum states. Its working principle is to use the superposition state of quantum bits to store information. Compared with traditional binary storage, quantum storage has the following advantages: 1. Higher storage density: a quantum bit can represent multiple states at the same time; 2. Safer storage: any unauthorized measurement will cause the quantum state to collapse, thereby detecting intrusion; 3. Faster reading speed: quantum parallelism greatly improves data reading efficiency. In specific implementation, the following schemes can be adopted: 1. Use superconducting quantum bits as storage units, and maintain the operating temperature at 20 millikelvin left 2; 2. Extend the coherence time of the quantum state through quantum decoherence suppression technology; 3. Use entangled state encoding to improve storage reliability.

[0026] S1.2: Generate a first quantum bit sequence based on the principle of quantum entanglement, and send the first quantum bit sequence to a receiving end.

[0027] It should be noted that quantum entanglement is a basic phenomenon in quantum mechanics. When there is an entangled relationship between two or more particles, the change in the state of one particle will immediately affect the state of other particles, and this association is not limited by distance. This step uses this principle to generate a secure quantum bit sequence. In the process of electronic file transmission, quantum entanglement provides a basic guarantee for secure communication. The system first generates a pump light with a wavelength of 405nm through a titanium sapphire laser. The beam is parametrically down-converted through a nonlinear crystal (such as a BBO crystal) to generate an entangled photon pair with a wavelength of 810nm. These entangled photon pairs are adjusted by wave plates to form a specific polarization state, and their entanglement is verified by quantum state tomography technology to maintain quantum coherence. The entire process is completed in an integrated quantum bit sequence generation system, which includes a quantum light source module for generating high-quality single photons or entangled photon pairs, a quantum state manipulation module for precise control of the quantum state of photons, a quantum state detection module for verifying the sequence quality, and a synchronization control module to ensure the precise timing synchronization of the transmitter and receiver, thereby establishing a reliable quantum communication infrastructure.

[0028] S1.3: Generate a quantum key through the BB84 protocol based on the first quantum bit sequence and the second quantum bit sequence fed back by the receiving end.

[0029] S1.3.1: Calculate the measurement basis consistency of the first quantum bit sequence and the second quantum bit sequence to obtain quantum bit measurement basis consistency data; S1.3.2: If the qubit measurement basis consistency data is greater than a preset threshold, the corresponding qubit value in the first qubit sequence is retained as the key data to be screened; S1.3.3: If the bit error rate of the key data to be screened is less than the preset bit error rate, the key data to be screened will be used as the quantum key.

[0030] After obtaining the quantum bit sequence, the system uses the BB84 quantum key distribution protocol to generate a secure key. The security of this protocol is derived from the basic principles of quantum mechanics. In specific implementation, the sender uses a quantum random number generator to select a linear polarization basis (|H>,|V>) or a diagonal polarization basis (|+45°>,|-45°>) to encode photons, and the receiver also randomly selects a measurement basis to measure the quantum state; then the two parties exchange basis information through a classical channel, retaining only the bits measured using the same basis as the original key, and detecting whether there is eavesdropping through random sampling. The system also integrates a decoy state method to defend against photon number splitting attacks, uses efficient error correction coding to improve key generation efficiency, and implements automated phase compensation and polarization compensation mechanisms to ensure that quantum keys can be generated stably and reliably in actual application environments (such as government affairs, finance, and medical fields), laying a secure foundation for subsequent encrypted file transmission.

[0031] S2: Use quantum keys to perform quantum encryption on electronic files to form encrypted file data containing quantum state information.

[0032] S2.1: Read the electronic file from the quantum memory and convert it into a quantum state data stream, wherein the quantum state data stream includes multiple quantum state information units; the quantum state information unit includes position information and value information.

[0033] Specifically, before quantum encryption, the system needs to convert the classical electronic archive data into quantum state form. First, the electronic archive in the quantum memory is extracted through the quantum state reading circuit. This process uses superconducting quantum bit array technology and operates in an extremely low temperature environment (about 20 millikelvin) to maintain quantum coherence. During the conversion process, the system divides the archive data into fixed-size data blocks, and each data block is mapped to the corresponding quantum state information unit. These quantum state information units use a composite encoding scheme: spatial position information is encoded using the orbital angular momentum state of photons, and numerical information is encoded using the polarization state of photons. Through quantum state tomography technology, the system can accurately prepare these quantum states so that each information unit can accurately express the digital characteristics of the original archive while maintaining the integrity and fidelity of the quantum state. The entire conversion process is completed in a specially designed quantum optical path system, which integrates high-precision quantum state preparation modules, phase compensation modules, and quantum state verification modules to ensure that the converted quantum state data stream has a high degree of stability and reliability.

[0034] S2.2: Use the quantum key to perform quantum state superposition operation on the quantum state data stream to generate encrypted archive data, which includes an encrypted quantum state information sequence.

[0035] Specifically, this step implements the actual quantum encryption process. First, the present invention inputs the quantum key obtained through the BB84 protocol into the quantum decomposer, which uses quantum Fourier transform technology to convert the quantum key into a series of quantum key components. Each key component contains specific amplitude coefficients and phase coefficients, which are precisely controlled by the high-precision quantum state regulation of the present invention. Subsequently, the present invention starts the quantum state superposition processor to perform quantum state superposition operations on each quantum state information unit in the quantum state data stream and the corresponding key component. This process uses controlled quantum gate operations to establish a complex entanglement relationship between the original quantum state and the key quantum state by regulating the interaction between quantum bits. Finally, the present invention recombines all encrypted quantum state units according to preset timing rules to form a complete encrypted archive data stream. The entire encryption process makes full use of the superposition principle and entanglement effect of quantum mechanics, so that the encrypted data has the security guaranteed by quantum mechanics, and any unauthorized measurement attempt will cause the quantum state to collapse, thereby being detected by the present invention.

[0036] S2.2.1: Decompose the quantum key into multiple quantum key components, which include amplitude coefficients and phase coefficients. Quantum key decomposition is a key preprocessing step for quantum encryption. The present invention adopts a high-performance quantum state decomposer, which works based on the quantum adiabatic evolution algorithm. Specifically, the quantum key is first loaded into a quantum register, and then converted to a specific representational basis through a series of quantum gate operations. In this process, the present invention uses a quantum phase estimation algorithm to extract phase information, and determines the amplitude coefficient through quantum amplitude amplification technology. Error correction coding is used in the precise extraction of these components to ensure the accuracy of the decomposition results. The final quantum key components are temporarily stored in the quantum buffer, waiting to be used in subsequent encryption operations. The entire decomposition process is completed at an extremely low decoherence rate, ensuring the integrity of the quantum information.

[0037] S2.2.2: Perform quantum state superposition on each quantum state information unit in the quantum state data stream and the corresponding quantum key component to form an encrypted quantum state unit, which includes entangled state information. In this core encryption step, the present invention uses high-precision quantum state manipulation technology to realize the superposition operation of quantum states. First, the present invention imports the quantum state information unit and the corresponding quantum key component into the quantum processing unit through a quantum switch network. In this unit, a precisely controlled quantum gate sequence is used to realize the interaction between the two quantum states. This process is similar to the preparation of quantum entangled states, but it is more complicated and requires precise control of the intensity and time of the interaction. The present invention uses pulsed laser technology to precisely control quantum gate operations and realizes precise superposition of quantum states through local phase modulation. In this process, the original information is encoded into a high-dimensional quantum Hilbert space to form an encrypted quantum state unit with multi-body entanglement characteristics. This encryption method uses the non-cloning property of quantum states to provide theoretically unconditional security protection for data.

[0038] S2.2.3: The encrypted quantum state units are combined according to a preset timing relationship to generate encrypted archive data, and the encrypted archive data includes multiple encrypted quantum state units. The final combination step requires precise timing control and quantum state protection. The present invention uses a quantum synchronization controller, which works based on the ultra-high precision time reference provided by the atomic clock. Each encrypted quantum state unit is assigned a unique time label, which is used for subsequent precise recombination. The present invention uses quantum error correction codes to protect these quantum states to prevent decoherence during transmission. During the combination process, quantum multiplexing technology is used to encode multiple quantum state units into the same quantum channel, which significantly improves the transmission efficiency. At the same time, the present invention also realizes real-time quantum state integrity check and monitors the quality of encrypted archive data through quantum state tomography technology. The encrypted archive data finally formed has a complete timing structure, which is convenient for the receiving end to perform accurate decryption operations.

[0039] S3: The encrypted archive data is transmitted online through the quantum communication channel, and the receiving end uses the corresponding quantum key to decrypt and restore it to complete the secure transfer of the archive.

[0040] S3.1: Encoding the encrypted archive data in quantum states at the sending end to generate a quantum communication carrier signal, which includes multiple quantum entangled states.

[0041] Specifically, first, the collected quantum communication carrier signal is input into the quantum state reconstructor. If the intensity of the quantum communication carrier signal is lower than a preset threshold, the quantum signal amplification module is started to amplify the quantum communication carrier signal. The quantum state reconstructor includes a quantum interferometer and a quantum state tomography system. Secondly, extract the phase information and amplitude information in the quantum communication carrier signal. If the error value of the phase information is greater than a first preset value, the quantum error correction module is triggered to perform phase correction. If the error value of the amplitude information is greater than a second preset value, the quantum error correction module is triggered to perform amplitude correction. The phase information and amplitude information are used to reconstruct the quantum entangled state. Finally, the entanglement degree of the reconstructed quantum entangled state is calculated. If the entanglement degree is less than the third preset value, the reconstruction step of the quantum entangled state is re-executed. If the entanglement degree is greater than or equal to the third preset value, the quantum entangled state is converted into encrypted archive data.

[0042] S3.2: Transmit the quantum communication carrier signal to the receiving end through the quantum communication channel, and the quantum communication channel includes the optical fiber quantum channel and the free space quantum channel.

[0043] S3.3: Collect the quantum communication carrier signal at the receiving end and perform quantum state decoding to obtain encrypted archive data. Quantum state decoding includes the reconstruction of the quantum entangled state.

[0044] S3.4: Use quantum keys to perform decryption operations on encrypted archive data to restore electronic archives. The decryption operations include inverse transformation of quantum states.

[0045] Preferably, the risk of signal duplication in traditional communications is fundamentally avoided through the design of quantum state coding and quantum communication carrier; the dual-channel transmission mechanism improves the adaptability of the system and solves the communication needs in different scenarios; the innovative introduction of multiple error judgment and correction mechanisms significantly improves the reliability of quantum information transmission; the entanglement threshold judgment in the quantum state reconstruction process ensures high-fidelity restoration of information and overcomes the channel noise interference problem in traditional quantum communications; and finally, accurate decryption is achieved through quantum state inverse transformation, which ensures data integrity while avoiding the computational complexity of the traditional decryption process.

[0046] In summary, the present invention organically combines quantum key distribution, quantum encryption and quantum communication technology. This solution realizes the secure storage of electronic archives through quantum memory, solving the security threats faced by traditional storage; using the BB84 protocol to generate quantum keys, fundamentally guarantees the security of key distribution; using quantum state superposition operations for encryption, significantly improves the encryption strength; through quantum communication carrier transmission and multiple error correction mechanisms, high-fidelity transmission of archive data is achieved. While ensuring communication security, the overall solution also has strong practicality and scalability. It is particularly suitable for sensitive data transmission in government affairs, finance, medical care and other fields, and provides a new technical path for the safe circulation of electronic archives. Compared with the existing technology, this solution not only realizes the unconditional secure transmission of information in theory, but also improves the reliability and stability of the system in practical applications through multiple protection mechanisms.
