The quantum entanglement phenomenon is widely applied to the field of quantum communication, and can realize high-safety information transmission; by way of example, quantum entanglement communications have at least the following advantages:

Environmental protection: the single photon authentication technology does not need to use a large amount of energy and resources, has lower environmental impact, and accords with the concept of sustainable development.
The method and system for transmitting bank data according to the embodiments of the present application require special quantum cryptography equipment, and require that the bank and the customer keep synchronization during transmission to ensure that the entangled state can be decrypted correctly.
Referring to fig. 1, fig. 1 is a flowchart of a method for transmitting bank data applied to a client according to an embodiment of the present application, where the method for transmitting bank data includes the following steps:
s110: generating customer entangled state data, wherein the customer entangled state information comprises first entangled state information and second entangled state information in a quantum entangled state;

This means that in the data transmission of banks, by establishing an entangled state, the sender and the receiver can perform secure communication over a long distance and cannot be eavesdropped and tampered with;
2. non-replicability of quantum entanglement: the quantum entangled state has the property of being unclonable, i.e., it is not possible to prepare exactly the same entangled state. This means that any attempt to replicate or eavesdrop on the entangled state will cause the quantum state to change, thus being detected by the receiving party, ensuring the security of the data transmission;
3. Quantum entangled non-tamperability: the quantum entanglement authentication technology judges whether the entanglement is tampered or eavesdropped through the authentication technology, and if the entanglement is tampered or eavesdropped, the receiver immediately stops data transmission, so that the integrity and the safety of the data transmission are ensured;
4. quantum key distribution: in banking data transmission, quantum entanglement is used to distribute keys, and a sender and a receiver can establish a secure key by measuring entanglement. This key is known only to the sender and the receiver and cannot be obtained by others. Due to the uncopyability and the uncopyable property of quantum entanglement, the quantum entanglement cannot be eavesdropped or tampered, and the safety of data transmission is ensured;
5. high efficiency of authentication technology: the quantum entanglement authentication technology can realize rapid, safe and accurate data transmission, and meanwhile, can realize efficient authentication through some techniques based on wavelength division multiplexing, thereby ensuring the safety of data transmission;
in summary, based on the quantum entanglement authentication technology, the security of the secure transmission of the bank data material can be ensured, the confidentiality, the integrity and the security of the data transmission are ensured through the quantum key distribution and the authentication technology, and the eavesdropping, the tampering and the repudiation can be effectively prevented.

It should be noted that, the transmission method of the bank data applied to the bank end shown in fig. 3 and fig. 4 corresponds to the transmission method of the bank data applied to the client end shown in fig. 1 and fig. 2, and in order to avoid repetition, the description is omitted here.
In some implementation scenarios, the implementation steps of the quantum entanglement authentication in the bank data transmission are as follows in combination with the transmission method of bank data shown in fig. 1 to 4:
1. generating entanglement state: banks and customers respectively create a pair of entanglement states, i.e. there is entanglement between two qubits, their states being related, no matter how far apart they are. Entangled states are created by the interaction of qubits, which can be created using pairs of qubits;
2. distributing entanglement state: the bank and the customer respectively reserve own entanglement state, and the other entanglement state is transmitted to the other party through the optical fiber. The transmission process needs to adopt a quantum key distribution protocol to protect photon transmission so as to prevent interception or tampering in the transmission process;
3. authentication: after receiving the entangled state of the other party, the bank and the client authenticate the other party. If the authentication passes, the received entanglement is indicated to be correct, and the next operation can be continued. If the authentication is not passed, the transmission needs to be interrupted and restarted;
4. Quantum gate operation: the bank and customer operate on the respective retained entangled state using a quantum gate operation to encrypt the bank material. In this process, a series of quantum gate operations, such as single bit gates, CNOT gates, etc., may be employed to complete the encryption process;
5. measurement: and the client measures the encrypted entanglement state to obtain the original data transmitted by the bank.
In some embodiments, the quantum key distribution protocol is a quantum entanglement-based encryption method, and a secure key can be established between two communicating parties, where the key can only be held together by both parties. The secret key can be used for symmetric encryption, so that the confidentiality of communication is ensured.
The following is a quantum key distribution (Quantum Key Distribution, QKD) protocol based on quantum entanglement:
1. the first step of quantum key distribution is to establish quantum entanglement pairs; both parties Alice and Bob of communication respectively prepare a pair of quantum bits, and quantum entanglement pairs are prepared through a quantum entanglement generator;
2. alice and Bob respectively measure the quantum bits at hand and send the measurement results to the other party;
3. alice and Bob disclose the measurement results and compare their results. If the measurements agree, then it is stated that their quantum entanglement pair is valid, and these qubits can be used as keys. If the measurement results are inconsistent, an eavesdropper exists between the two communication parties, and the protocol needs to be re-executed;
4. Alice and Bob use the negotiated secret key to encrypt and decrypt, thereby ensuring the confidentiality of the data;
through the steps, the quantum key distribution protocol can ensure that both communication parties establish a safe key which can only be held by both parties together and effective information can not be obtained by eavesdroppers. This approach may provide a very high level of security, making the bank data transfer more reliable and secure.
