Protecting information in a quantum world: from cryptography to error correction

Jincheng Zhang

Quantum information cryptography offers the potential for unprecedented security through the use of quantum mechanics. This paper presents a novel quantum information cryptography protocol designed to establish unbreakable encryption utilizing entanglement and quantum error correction principles. We explore a quantum key distribution (QKD) protocol that incorporates a novel error correction mechanism based on quantum error correction principles. The design focuses on creating a robust and resilient encryption system capable of resisting known attacks. The proposed protocol utilizes entanglement to generate a shared secret key, which is then protected by a quantum error correction mechanism. This paper details the protocol's architecture, error correction strategies, and potential security implications.

A general method is proposed for privacy protection upon correction of errors in primary keys in quantum cryptography through an open communication channel. By the example of the cascade procedure for correcting errors, a method is described for removing information sent through an open communication channel when cleaning a key. The critical percentage is found for the quantum cryptography protocol BB84 to which the cascade error correction method with deletion guarantees the security of the final key. The method proposed for removing information sent through the open communication channel is quite general and can be used for many cleaning protocols for primary keys in quantum cryptography.

Since 2000, several landmark results in quantum information have catapulted the field to one of the most exciting in science. From the demonstration of Shor’s factorisation algorithm that threatens the long-term security of public-key cryptography, to the teleportation of super-position states, the demonstration of error-correcting codes and the development of topologically protected qubits, our ability to control the quantum world is ever increasing. Matched by elegant experiments to test the fundamentals of quantum physics, such as the recent demonstration of the loop-hole free violation of Bell's inequality, 1 , 2 these exciting achievements are all emerging just at the time when information technology is beginning to enter the quantum regime.
