Abstract

The invention belongs to the technical field of quantum information sharing, and discloses a quantum secret sharing method and sharing system based on quantum walk, and the method comprises the steps:enabling a secret distributor to encode secret information to be shared into a quantum state according to a rule, and enabling an encoding particle to be split into two parts; invisibly transferringthe two pieces of encrypted information to a first participant and a second participant through a quantum walking system; and the first participant and the second participant decrypt the secret information of the secret distributor through cooperation. Characteristics of the quantum walking system are used for invisible state transfer of unknown particles, entanglement is spontaneously generated among the particles, and preparation of entangled particles in a particle preparation stage is avoided to complete invisible state transfer of the particles. According to the quantum secret sharing method based on quantum walking, an invisible state transfer method based on quantum walking is combined with a coding rule, and the quantum secret sharing method based on quantum walking is completed.

Description

technical field

[0001] The invention belongs to the technical field of quantum information sharing, and in particular relates to a quantum secret sharing method and a sharing system based on quantum walks. Background technique

[0002] At present, the closest existing technology: since Bennett et al. proposed the BB84 protocol, quantum key distribution (QKD) and quantum communication (QC) have become important topics in quantum cryptography, and various QKD protocols and QC protocols have been proposed. The development of QKD and QC has promoted the research of quantum secret sharing (QSS), making QSS an important branch of quantum cryptography. Suppose the secret distributor Alice wants to share a secret information with participants Bob and Charlie, when only Bob and Charlie can obtain Alice’s complete secret information through mutual honest cooperation, no one can obtain Alice’s complete secret information through sub-information or dishonest operations alone informatio...
