Title:
量子情報通信システム、量子情報中継装置、量子情報通信方法およびプログラム
Document Type and Number:
Japanese Patent JP4162687
Kind Code:
B2
Abstract:
A quantum repeater apparatus performs an entanglement swapping (ES) process for sharing an EPR pair with another node, and performs an entanglement purification protocol (EPP) process with the node with which the EPR pair is shared. The quantum repeater apparatus selects, when performing a last EPP process, a classical channel different from at least one of a classical channel used for a last ES process and used for any one of ES processes that have been performed before the last ES process, and a classical channel used for any one of EPP processes that have been performed before.
