Abstract

The invention belongs to the technical field of computer software and discloses a method and a system for increasing the number of quantum entanglement interfaces. The system comprises a quantum measurement module, an entanglement state preparation module, a channel acceleration module of a basic link, a channel acceleration module of a long link and an incremental preparation module. The quantumis described as the complex inner product vector space of the system state space by the quantum measurement module. The entanglement generation module realizes many quantum communication tasks, such as dense quantum coding, quantum teleportation and so on, realizes quantum computation and prepares the initial entanglement effectively. The whole process of quantum computation deals with the information encoded in quantum states. The invention establishes a quantum channel between two non-adjacent interfaces through a relay interface through a channel acceleration module of a long link.

Description

technical field [0001] The invention belongs to the technical field of computer software, and in particular relates to a method and system for increasing the number of quantum entanglement interfaces. Background technique [0002] At present, the commonly used existing technologies in the industry are as follows: quantum interfaces are used to realize the coherent conversion of quantum information between photons and storage particles (usually atoms), and are important for connecting quantum memory or quantum computing units with optical quantum communication channels. interface. Similar to the wide application of classical interfaces, quantum interfaces are basic components in the field of quantum information. Realizing entanglement between quantum interfaces is a basic requirement for building quantum networks and the future quantum Internet. In quantum information science, photons have the fastest transmission speed and are the best carrier for disseminating quantum info...
