Quench dynamics of topological quantum phase transition in Wen-plaquette model
Long Zhang, Su-Peng Kou, Youjin Deng
We study the quench dynamics of the topological quantum phase transition in the two-dimensional transverse Wen-plaquette model, which has a phase transition from a Z2 topologically…
Interference of overlap-free entangled photons with a Mach-Zehnder-like interferometer
Xian-Min Jin, Cheng-Zhi Peng, Tao Yang +1
Using spontaneous parametric down conversion and a 50:50 beam splitter, we generate coaxial polarization-entangled photon pairs, of which the two photons are far separated from eac…
Quantum interface between frequency-uncorrelated down-converted entanglement and atomic-ensemble quantum memory
Xian-Min Jin, Jian Yang, Han Zhang +15
Photonic entanglement source and quantum memory are two basic building blocks of linear-optical quantum computation and long-distance quantum communication. In the past decades, in…
Light pulse in -type cold atomic gases
Ran Wei, Bo Zhao, Youjin Deng +3
We investigate the behavior of the light pulse in -type cold atomic gases with two counterpropagating control lights with equal strength by directly simulating the dynamic…
