Abstract

This paper addresses an individual attack strategy against BBM92 protocol. By constructing a map from the measurement result to the initial state, we find this individual attack is essentially equivalent to the discrimination attack against BB84 protocol. The optimal tradeoff between the guessing capability and disturbance quantity is explicitly deducted and the optimal measurement that saturates the tradeoff bound is also presented.
