Spin-orbit coupling induced geometric squeezing in rotating Bose-Einstein condensates
Fei Zhu, Chunxia Guo, Rui Zhang +3
Squeezed states play a key role in diverse frontiers of quantum physics. Geometrically squeezed states, a squeezed state in the orbital phase space of rotating Bose-Einstein conden…
Higher-order exceptional points and enhanced quantum squeezing in a pseudo-Hermitian semiconductor optomechanical system
Zi-Wei Jiang, Yan-Zi Jing, Zhen-Sen Lin +4
We investigate higher-order exceptional points and quantum squeezing of exciton polaritons in a pseudo-Hermitian semiconductor optomechanical system. We show that a third-order exc…
Quantum-enhanced distributed network sensing using multiple quantum resources
Rui Zhang, Zi-Yu Zhou, Wen-Quan Yang +3
We propose a theoretical scheme for quantum enhanced distributed network sensing, targeting multiphase estimation by leveraging multiple quantum resources. Specifically, we investi…
Nonreciprocal entanglement in exciton optomechanics with an optical parametric amplifier
Zhen-Sen Lin, Rui Zhang, Zi-Wei Jiang +4
We study nonreciprocal bipartite and tripartite entanglement in a spinning exciton-optomechanical system (EOMS) with an optical parametric amplifier (OPA). We demonstrate that nonr…
