Generation of spin squeezing via a fully quantum degenerate parametric amplifier
Yang Liu, Jie Song, Wei Qin +2
Spin squeezing is one of the most attractive methods for realizing high-precision metrology. In this paper, we propose a protocol for generating spin squeezing in an atomic ensembl…
Sudden change of the photon output field marks phase transitions in the quantum Rabi model
Ye-Hong Chen, Yuan Qiu, Adam Miranowicz +6
The experimental observation of quantum phase transitions predicted by the quantum Rabi model in quantum critical systems is usually challenging due to the lack of signature experi…
Observation of a superradiant phase transition with emergent cat states
Ri-Hua Zheng, Wen Ning, Ye-Hong Chen +15
Superradiant phase transitions (SPTs) are important for understanding light-matter interactions at the quantum level, and play a central role in criticality-enhanced quantum sensin…
Detecting a single atom in a cavity using the nonlinear medium
Dong-Liang Chen, Ye-Hong Chen, Yang Liu +3
We propose a protocol for detecting a single atom in a cavity with the help of the nonlinear medium. When the nonlinear medium is driven by an external laser fi…
Enhanced-Fidelity Ultrafast Geometric Quantum Computation Using Strong Classical Drives
Ye-Hong Chen, Adam Miranowicz, Xi Chen +2
We propose a general approach to implement nonadiabatic geometric single- and two-qubit gates beyond the rotating wave approximation (RWA). This protocol is compatible with most op…
