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…
Quantum-enhanced Electrometer based on Microwave-dressed Rydberg Atoms
