Generation of a non-zero discord bipartite state with classical second-order interference

2017 · Optics Express

We report an investigation on quantum discord in classical second-order interference. In particular, we theoretically show that a bipartite state with D = 0.311 of discord can be generated via classical second-order interference. We also …

User-independent optical path length compensation scheme with sub-ns timing resolution for 1xN quantum key distribution network system

2020 · arXiv (Cornell University)

Quantum key distribution (QKD) networks constitute promising solutions for secure communication. Beyond conventional point-to-point QKD, we developed 1xN QKD network systems with a sub-ns resolution optical path length compensation scheme. With a practical plug-and-play QKD …
