Generating large-scale Greenberger-Horne-Zeilinger-like states in lattice spin systems
Xuanchen Zhang, Yaofeng Chen, Yong-Chun Liu
Greenberger-Horne-Zeilinger (GHZ) state is a typical maximally entangled state which is pursued in both fundamental research and emerging quantum technologies. Preparing large-scal…
Exact steady state of quantum van der Pol oscillator: critical phenomena and enhanced metrology
Yaohua Li, Xuanchen Zhang, Yong-Chun Liu
Quantum criticality of open many-body systems has attracted lots of interest for emergent phenomena and universality. Here we present the exact steady state of the quantum van der…
Realization of the Non-endpoint Majorana Bound States in an Extended Kitaev Chain
Xuan Zhang, Cheng-Ming Miao, Qing-Feng Sun +1
We study the energy levels and transport properties of an extended Kitaev chain with a phase gradient. It is demonstrated that the hopping phase difference can effectively induce t…
Spin Squeezing through Collective Spin-Spin Interactions
Yanzhen Wang, Xuanchen Zhang, Yong-Chun Liu
Spin squeezing provides crucial quantum resource for quantum metrology and quantum information science. Here we propose that one axis-twisted (OAT) spin squeezing can be generated…
Fast Generation of GHZ-like States Using Collective-Spin XYZ Model
Xuanchen Zhang, Zhiyao Hu, Yong-Chun Liu
The Greenberger-Horne-Zeilinger (GHZ) state is a key resource for quantum information processing and quantum metrology. The atomic GHZ state can be generated by one-axis twisting (…
