Quantum phase transition of nonlocal Ising chain with transverse field in a resonator

Yu-Na Zhang, Xi-Wang Luo, Guang-Can Guo +2

We study the quantum phase transition in a spin chain with variable Ising interaction and position-dependent coupling to a resonator field. Such a complicated model, usually not pr…

2-GHz clock quantum key distribution over 260 km of standard telecom fiber

Shuang Wang, Wei Chen, Jun-Fu Guo +5

We report a demonstration of quantum key distribution (QKD) over a standard telecom fiber exceeding 50 dB in loss and 250 km in length. The differential phase shift QKD protocol wa…
