This letter proposes a novel key distribution protocol with no key exchange in advance, which is secure as the BB84 quantum key distribution protocol. Our protocol utilizes a phot...
In this work we present the principles of a flexible quantum key distribution (QKD) system using quadraturephase-shift-keying (QPSK) base and symbol encoding and dualthreshold bala...
