Quantum coherence is critical resource for applications in quantum technology, among which quantum-enhanced sensing represents a typical example.Compared with quantum metrology wit…
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…
Dissipation-accelerated entanglement generation
Xiao-Wei Zheng, Jun-Cong Zheng, Xue-Feng Pan +3
Dissipation is usually considered a negative factor for observing quantum effects and for harnessing them for quantum technologies. Here we propose a scheme for speeding up the gen…
