摘要：

We propose an experimental implementation of a particular attack against the BB84 quantum key distribution protocol, utilizing a 1 -> 3 asymmetric phase-covariant quantum cloning. Our eavesdropping strategy is numerically optimized to extract the information about the input state. The proposed cloning circuit is easily implementable with linear optics and its performances turn out to be well close to the optimum attack.
