Quantum processing method and device for transmission error detection, equipment and medium

The invention discloses a quantum processing method and device for transmission error detection, equipment and a medium. The method comprises the steps that a quantum state is prepared at a communication sending end according to a quantum key distribution protocol, and double-track coding is carried out; transmitting the coded quantum state by using a Fouli channel to obtain transmission information data of the quantum state to be detected in the Fouli channel; designing an error detection circuit to pre-screen single quantum bit errors in the quantum state to be detected; and the parameterized quantum circuit is trained as a quantum machine learning model to perform amplitude amplification on a correct state in the to-be-amplified quantum states to obtain a transmission quantum state. According to the method, errors in quantum transmission are detected through coding design, channel selection error detection and amplitude amplification through quantum machine learning, the probability of detecting the correc
