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…
Quantum Twin Interferometers
Wei Du, Shuhe Wu, Dong Zhang +6
Quantum-correlated interferometer is a newly emerging tool in quantum technology that offers classical-limit-breaking phase sensitivity. But to date, there exists a configurational…
Quantum Locking of Intrinsic Spin Squeezed State in Earth-field-range Magnetometry
Peiyu Yang, Guzhi Bao, Jun Chen +3
In the Earth-field range, the nonlinear Zeeman (NLZ) effect has been a bottleneck limiting the sensitivity and accuracy of atomic magnetometry from physical mechanism. To break thi…
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…
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,…
Quantum dense metrology by an SU(2)-in-SU(1,1) nested interferometer
Wei Du, J. F. Chen, Z. Y. Ou +1
With the help of quantum entanglement, quantum dense metrology (QDM) is a technique that can perform the joint estimates of two conjugate quantities such as phase and amplitude mod…
Absolute sensitivity of phase measurement in an SU(1,1) type interferometer
Wei Du, Jun Jia, J. F. Chen +2
Absolute sensitivity is measured for the phase measurement in an SU(1,1) type interferometer and the results are compared to that of a Mach-Zehnder interferometer operated under th…
