We demonstrate the decoy-state quantum key distribution (QKD) with one-way quantum
communication in polarization space over 102 km. Further, we simplify the experimental …

We report an implementation of decoy-state quantum key distribution (QKD) over 200 km
optical fiber cable through photon polarization encoding. This is achieved by constructing …

To increase dramatically the distance and the secure key generation rate of quantum key
distribution (QKD), the idea of quantum decoys—signals of different intensities—has recently …

Polarization-encoding provides a promising approach for the practical quantum key
distribution (QKD) system due to the simple encoding and decoding method. Here we …

We demonstrate the first implementation of polarization encoding measurement-device-
independent quantum key distribution (MDI-QKD), which is immune to all detector side …

In this paper, we study the feasibility of conducting quantum key distribution (QKD) together
with classical communication through the same optical fiber by employing dense …

Measurement-device-independent quantum key distribution (MDI QKD) removes all detector
side channels and enables secure QKD with an untrusted relay. It is suitable for building a …

In free-space quantum key distribution (QKD), the sensitivity of the receiver's detector
channels may depend differently on the spatial mode of incoming photons. Consequently …

Channel loss seems to be the most severe limitation on the practical application of long
distance quantum key distribution. The idea of twin-field quantum key distribution can …

We perform a proof-of-principle demonstration of the measurement-device-independent
quantum key distribution protocol using weak coherent states and polarization-encoded …
