Increasing the security of the ping–pong protocol by using many mutually unbiased bases

Increasing the security of the ping–pong protocol by using many mutually unbiased bases In this paper we propose an extended version of the ping–pong protocol and study its security. The proposed protocol incorporates the usage of mutually unbiased bases in the control mode. We show that, by increasing the number of bases, it is possible to improve the security of this protocol. We also provide the upper bounds on eavesdropping average non-detection probability and propose a control mode modification that increases the attack detection probability. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Quantum Information Processing Springer Journals
