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 $…
Generation and storage of spin squeezing via learning-assisted optimal control
Qing-Shou Tan, Mao Zhang, Yu Chen +2
The generation and storage of spin squeezing is an attracting topic in quantum metrology and the foundations of quantum mechanics. The major models to realize the spin squeezing ar…
Fluctuation-enhanced quantum metrology
Yu Chen, Hongzhen Chen, Jing Liu +2
The main obstacle for practical quantum technology is the noise, which can induce the decoherence and destroy the potential quantum advantages. The fluctuation of a field, which in…
Operational definition of a quantum speed limit
Yanyan Shao, Bo Liu, Mao Zhang +2
The quantum speed limit is a fundamental concept in quantum mechanics, which aims at finding the minimum time scale or the maximum dynamical speed for some fixed targets. In a larg…
Quantum Fisher information matrix and multiparameter estimation
Jing Liu, Haidong Yuan, Xiao-Ming Lu +1
Quantum Fisher information matrix (QFIM) is a core concept in theoretical quantum metrology due to the significant importance of quantum Cramér-Rao bound in quantum parameter estim…
Multiqubit matter-wave interferometry under decoherence and the Heisenberg scaling recovery
Yanming Che, Jing Liu, Xiao-Ming Lu +1
Most matter-wave interferometry (MWI) schemes for quantum sensing are so far evaluated in ideal situations without noises. In this work, we provide assessments of generic multiqubi…
