Title:
BUTTERFLY NETWORK ENCODING METHOD BASED ON BIDIRECTIONAL HYBRID QUANTUM INFORMATION EXCHANGE
Document Type and Number:
WIPO Patent Application WO/2022/193942
Kind Code:
A1
Abstract:
Disclosed in the present invention is a butterfly network encoding method based on bidirectional hybrid quantum information exchange, comprising: constructing a butterfly network model, enabling a source node, a destination node, and a control party to cross-share a 5-bit Brown channel, and performing particle allocation; the destination node first introducing auxiliary particles and performing CNOT operation; two pairs of dialogue parties selecting suitable measurement bases to measure particles; the dialogue party sending the measurement result to the other party; if the control party agrees with information exchange between the dialogue parties, the control party executing single-particle measurement and sending the measurement results to the dialogue parties; the dialogue parties sending the measurement results to corresponding intermediate nodes; the intermediate nodes sending information codes to the four dialogue parties; the dialogue parties performing decoding and executing suitable unitary operations to restore to target states. The present invention uses the butterfly network, thereby greatly increasing the information transmission rate; the source node and the destination node have the same status, thereby expanding an application range of a quantum channel, and reducing the operation difficulty coefficient.
