Zero-error attacks and detection statistics in the coherent one-way protocol for quantum cryptography |
Abstract | ||
|---|---|---|
This is a study of the security of the Coherent One-Way (COW) protocol for quantumcryptography, proposed recently as a simple and fast experimental scheme. In thezero-error regime, the eavesdropper Eve can only take advantage of the losses in thetransmission. We consider new attacks, based on unambiguous state discrimination,which perform better than the basic beam-splitting attack, but which can be detectedby a careful analysis of the detection statistics. These results stress the importance oftesting several statistical parameters in order to achieve higher rates of secret bits. |
