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 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…
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…
