Atom-light hybrid interferometer for atomic sensing with quantum memory
Xingchang Wang, Xinyun Liang, Liang Dong +7
Quantum memories feature a reversible conversion of optical fields into long-lived atomic spin waves, and are therefore ideal for operating as sensitive atomic sensors. However, up…
Novel coupling between charge order and time-reversal-symmetry-breaking superconductivity
Quanxin Hu, Lingfeng Zhang, Yu Zheng +9
The interplay between charge-density waves (CDWs), which break translational symmetry, and spatially homogeneous superconductivity, which breaks global U(1) gauge symmetry, can giv…
Atom-light-correlated quantum interferometer with memory-induced phase comb
Wenfeng Huang, Xinyun Liang, Jie Zhao +7
Precise phase measurements by interferometers are crucial in science for detecting subtle changes, such as gravitational waves. However, phase sensitivity is typically limited by t…
Optimal phase measurements in a lossy Mach-Zehnder interferometer
Wenfeng Huang, Xinyun Liang, Chun-Hua Yuan +2
In this work, we discuss two phase-measurement methods for the Mach-Zehnder interferometer (MZI) in the presence of internal losses and give the corresponding optimum conditions. W…
Protection of noise squeezing in a quantum interferometer with optimal resource allocation
Wenfeng Huang, Xinyun Liang, Baiqiang Zhu +4
Interferometers are crucial for precision measurements, including gravitational waves, laser ranging, radar, and imaging. The phase sensitivity, the core parameter, can be quantum-…
Photon blockade in a bi-mode nonlinear nano-cavity embedded with a quantum-dot
Xinyun Liang, Zhenglu Duan, Qin Guo +3
We study the interaction between a quantum-dot and a bi-mode micro/nano-optical cavity composed of second-order nonlinear materials. Compared with the Jaynes-Cummings (J-C) model,…
Conventional and unconventional photon blockade effects in an atom-cavity system
Xinyun Liang, Zhenglu Duan, Qin Guo +3
A two-level system interacting with a cavity field is an important model for investigating the photon blockade (PB) effect. Most work on this topic has been based on the assumption…
