Optimal Scheme for Quantum Metrology
Jing Liu, Mao Zhang, Hongzhen Chen +2
Quantum metrology can achieve far better precision than classical metrology, and is one of the most important applications of quantum technologies in the real world. To attain the…
Single-photon-triggered spin squeezing with decoherence reduction in optomechanics via phase matching
Zhucheng Zhang, Lei Shao, Wangjun Lu +4
Quantum spin squeezing is an important resource for quantum information processing, but its squeezing degree is not easy to preserve in an open system with decoherence. Here, we pr…
Bhatia-Davis formula in the quantum speed limit
Jing Liu, Zibo Miao, Libin Fu +1
The Bhatia-Davis theorem provides a useful upper bound for the variance in mathematics, and in quantum mechanics, the variance of a Hamiltonian is naturally connected to the quantu…
Quantum metrology with precision reaching beyond- scaling through -probe entanglement generating interactions
Xing Deng, Shou-Long Chen, Mao Zhang +7
Nonlinear interactions are recognized as potential resources for quantum metrology, facilitating parameter estimation precisions that scale as the exponential Heisenberg limit of $…
