Creating a tunable spin squeezing via a time-dependent collective atom-photon coupling
Lixian Yu, Jingtao Fan, Shiqun Zhu +3
We present an experimentally feasible method to produce a large and tunable spin squeezing when an ensemble of many four-level atoms interacts simultaneously with a single-mode pho…

Quantum phases in circuit QED with a superconducting qubit array
Yuanwei Zhang, Lixian Yu, J. -Q. Liang +3
Circuit QED on a chip has become a powerful platform for simulating complex many-body physics. In this report, we realize a Dicke-Ising model with an antiferromagnetic nearest-neig…
