Quantum-Enhanced Atomic Sensor via Spin Nonequilibrium Criticality
Ding Huang, Minwei Shi, Guzhi Bao +2
The sensitivity of quantum sensors is fundamentally constrained by the standard quantum limit (SQL) arising from intrinsic quantum fluctuations. While non-classical resources like…
Quantum-elevated Chiral Discrimination for Bio-molecules
Yiquan Yang, Xiaolong Hu, Wei Du +4
Chiral discrimination of enantiomeric biomolecules is vital in chemistry, biology, and medicine. Conventional methods, relying on circularly polarized light, face weak chiroptical…
Near-perfect broadband quantum memory enabled by intelligent spinwave compaction
Jinxian Guo, Zeliang Wu, Guzhi Bao +4
Quantum memory, a pivotal hub in quantum information processing, is expected to achieve high-performance storage and coherent manipulation of quantum states, with memory efficiency…
Quantum Metrology with Higher-order Exceptional Points in Atom-cavity Magnonics
Minwei Shi, Guzhi Bao, Jinxian Guo +1
Exceptional points (EPs), which arose early from non-Hermitian physics, significantly amplify the system's response to minor perturbations, and they act as a useful concept to enha…
Quantum-enhanced Electrometer based on Microwave-dressed Rydberg Atoms
Shuhe Wu, Dong Zhang, Zhengchun Li +6
Rydberg atoms have been shown remarkable performance in sensing microwave field. The sensitivity of such an electrometer based on optical readout of atomic ensemble has been demons…
Sensing performance enhancement via asymmetric gain optimization in the atom-light hybrid interferometer
Zhifei Yu, Bo Fang, Shuying Chen +4
The SU (1,1)-type atom-light hybrid interferometer (SALHI) is a kind of interferometer that is sensitive to both the optical phase and atomic phase. However, the loss has been an u…
SU(2)-in-SU(1,1) Nested Interferometer for Highly Sensitive, Loss-Tolerant Quantum Metrology
Wei Du, Jia Kong, Jun Jia +6
We present experimental and theoretical results on a new interferometer topology that nests a SU(2) interferometer, e.g., a Mach-Zehnder or Michelson interferometer, inside a SU(1,…
A compact 3.5-dB squeezed light source with atomic ensembles
Guzhi Bao, Xiaotian Feng, Bing Chen +4
We reported a compact squeezed light source consisting of an diode laser near resonant on 87Rb optical D1 transition and an warm Rubidium vapor cell. The -4dB vacuum squeezing at 7…
