Mechanical Squeezed-Fock Qubit: Towards Quantum Weak-Force Sensing
Yi-Fan Qiao, Jun-Hong An, Peng-Bo Li
Mechanical qubits offer unique advantages over other qubit platforms, primarily in terms of coherence time and possibilities for enhanced sensing applications, but their potential…
Optical nonreciprocity induced by quantum squeezing in temperature sensitive optomechanical systems
Jun-Cong Zheng, Xiao-Wei Zheng, Xin-Lei Hei +6
We investigate single photon transmission and the statistical properties of photon correlations in microring optomechanical systems, where optical nonreciprocity is indu…
Non-Markovian dynamics with -type atomic systems in a single end photonic waveguide
Jun-Cong Zheng, Xiao-Wei Zheng, Xin-Lei Hei +6
In this work, we investigate the non-Markovian dynamical evolution of a -type atom interacting with a semi-infinite one-dimensional photonic waveguide via two atomic transition…
Single photon isolation and nonreciprocal frequency conversion in atom-waveguide systems
Jun-Cong Zheng, Xiao-Wei Zheng, Xin-Lei Hei +6
In this work, we utilize a two-level atom and a -type atom to link two identical waveguides, subsequently extending the model to a giant-atom configuration. Our analytical solu…
Nonreciprocal interaction and entanglement between two superconducting qubits
Yu-Meng Ren, Xue-Feng Pan, Xiao-Yu Yao +5
Nonreciprocal interaction between two spatially separated subsystems plays a crucial role in signal processing and quantum networks. Here, we propose an efficient scheme to achieve…
