Influence of Fibre Channel Pressure on Actual Quantum Bit Error Rate
摘要
Abstract
An actual peer to peer quantum key distribution experimental system of polarization encoding was built based on BB84 protocol under pressure testing conditions.Fibre channel pressure experiment about quantum key distribution was completed.The theoretical model of quantum bit error rate was established with positive operator valued measurement method.The research results show that under the same pressure,bit error rate increased with the increase of angle,the result was as theoretical arithmetic expected;and at the same angle,the bit error rate showed a gentle shock upward trend with the increase of pressure,and when the pressure exceeded a critical value,the bit error rate increased rapidly,approaching the limit,forcing the quantum key distribution system to reestablish a connection.关键词
