Efficient-phase-encoding protocols for continuous-variable quantum key distribution using coherent states and postselection
Ryo Namiki, Takuya Hirano
We propose efficient-phase-encoding protocols for continuous-variable quantum key distribution using coherent states and postselection. By these phase encodings, the probability of…

Security of Continuous-variable quantum cryptography using coherent states: Decline of postselection advantage
Ryo Namiki, Takuya Hirano
We investigate the security of continuous-variable (CV) quantum key distribution (QKD) using coherent states in the presence of quadrature excess noise. We consider an eavesdroppin…

A practical limitation for continuous-variable quantum cryptography using coherent states
Ryo Namiki, Takuya Hirano
In this letter, first, we investigate the security of a continuous-variable quantum cryptographic scheme with a postselection process against individual beam splitting attack. It i…
