Quantum key distribution provides secure keys with information-theoretic security ensured
by the principle of quantum mechanics. The continuous-variable version of quantum key …

Quantum cryptography is arguably the fastest growing area in quantum information science.
Novel theoretical protocols are designed on a regular basis, security proofs are constantly …

In this letter, we report on the advances toward the integration of our developed continuous
variables (CV) quantum key distribution (QKD) system in existing optical infrastructure and …

The secret key rate of a continuous-variable quantum key distribution (CV-QKD) system is
limited by excess noise. A key issue typical to all modern CV-QKD systems implemented …

A quantum channel is a physical media able to carry quantum signals. Quantum key
distribution (QKD) requires direct quantum channels between every pair of prepare-and …

We present a pilot-assisted coherent intradyne reception methodology for CV-QKD with true
local oscillator. An optically phase-locked reference tone, prepared using carrier …

Distributing cryptographic keys over public channels in a way that can provide information-
theoretic security is the holy grail for secure communication. This can be achieved by …

In the domain of continuous variable quantum key distribution (CV-QKD), a significant
challenge arises in achieving precise frequency synchronization, an issue commonly termed …

QKD technology is mature enough to be used beyond the usual single, point to point, link by
creating networks. Quantum ad hoc networks, where a separate, quantum-only network, is …

We develop and experimentally demonstrate a phase-sensitive continuous variable
quantum key distribution system with improved secure key rate. This is achieved using …
