Fast quantum state transfer and entanglement preparation in strongly coupled bosonic systems
Yilun Xu, Daoquan Zhu, Feng-Xiao Sun +2
Continuous U(1) gauge symmetry, which guarantees the conservation of the total excitations in linear bosonic systems, will be broken when it comes to the strong-coupling regime whe…
Detecting Einstein-Podolsky-Rosen steering in non-Gaussian spin states from conditional spin-squeezing parameters
Jiajie Guo, Feng-Xiao Sun, Daoquan Zhu +3
We present an experimentally practical method to reveal Einstein-Podolsky-Rosen steering in non-Gaussian spin states by exploiting a connection to quantum metrology. Our criterion…
Quantum computing with superconducting circuits in the picosecond regime
Daoquan Zhu, Tuomas Jaako, Qiongyi He +1
We discuss the realization of a universal set of ultrafast single- and two-qubit operations with superconducting quantum circuits and investigate the most relevant physical and tec…
Preparation of entangled states of microwave photons in a hybrid system via electro-optic effect
Daoquan Zhu, Pengbo Li
We propose to realize the two-mode continuous-variable entanglement of microwave photons in an electro-optic system, consisting of two superconducting microwave resonators and one…
