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…
Frequency Range Boosted Magnetometry Beyond the Spin Coherence Limit via Compressive Sensing
Ruiqi Wang, Peiyu Yang, Ding Huang +2
Free induction decay (FID) of spin precession serves as an essential tool for quantum sensing across diverse platforms. While extending spin coherence time remains critical for sen…
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 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…
