Implementation vulnerabilities in general quantum cryptography

Methods and implementation of quantum cryptography

Quantum mechanical properties of communication lines may be lead to new possibilities in the security of key distribution. By taking advantage of basic quantum mechanical principles, it may be possible to create secure systems that rely upon the physics of the system rather than computational or mathematical methods for security. In this paper, three possible protocols for quantum key distribut...

General immunity and superadditivity of two-way Gaussian quantum cryptography.

We consider two-way continuous-variable quantum key distribution, studying its security against general eavesdropping strategies. Assuming the asymptotic limit of many signals exchanged, we prove that two-way Gaussian protocols are immune to coherent attacks. More precisely we show the general superadditivity of the two-way security thresholds, which are proven to be higher than the correspondi...
