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 founded on the laws of physics could revolutionize the way in which
communication information is protected. Significant progresses in long-distance quantum …

We report the first continuous-variable quantum key distribution (CVQKD) experiment to
enable the creation of 1 Mbps secure key rate over 25 km standard telecom fiber in a coarse …

A new quantum dialogue protocol is designed by using the continuous-variable two-mode
squeezed vacuum states due to its entanglement property. The two communication parties …

We address the role of the phase-insensitive trusted preparation and detection noise in the
security of a continuous-variable quantum key distribution, considering the Gaussian …

We propose and experimentally demonstrate a continuous-variable quantum key
distribution (CV-QKD) protocol using dual-phase-modulated coherent states. We show that …

A continuous-variable quantum identity authentication protocol, which is based on quantum
teleportation, is presented by employing two-mode squeezed vacuum state and coherent …

We propose a scheme for continuous-variable quantum key distribution (CV-QKD) using the
subcarrier multiplexing technique which was employed in microwave photonics. This …

Continuous-variable quantum secret sharing (CVQSS) allows a legitimate user, ie, the
dealer, to share a string of secret keys with multiple distant users. These users cannot …

In a fiber-based continuous-variable quantum key distribution (CVQKD) system, to perform
the channel estimation, the channel transmittance is usually assumed to be a constant …
