Finite-Shot Sensitivity for Moment Estimation in Quantum Metrology
Shaowei Du, Shuheng Liu, Weidong Li +3
The quantum Cramér-Rao bound can be saturated only asymptotically and does not specify how many measurements are needed for a concrete estimator to approach it. We develop a finite…
From Spectral Singularities to Multipartite Entanglement Scaling at Higher-Order Exceptional Points
Chunlai Yang, Shuheng Liu, Xinyao Huang +2
Exceptional points (EPs) are non-Hermitian spectral singularities exhibiting fractional-power responses, yet their implications for multipartite entanglement of interacting quantum…
Metrological Sensitivity beyond Gaussian Limits with Cubic Phase States
Jiajie Guo, Shuheng Liu, Boxuan Jing +2
Cubic phase states provide the essential non-Gaussian resource for continuous-variable quantum computing. We show that they also offer significant potential for quantum metrology,…
Detection of non-Gaussian quantum correlations through measurement-after-interaction protocols
Jiajie Guo, Feng-Xiao Sun, Matteo Fadel +1
Additional state evolutions performed before measurement, also called measurement-after-interactions (MAI) protocols, have shown a great potential for increasing the sensitivity of…
Entanglement Dimensionality of Continuous Variable States From Phase-Space Quasi-Probabilities
Shuheng Liu, Jiajie Guo, Matteo Fadel +3
The dimensionality of entanglement, quantified by the Schmidt number, is a core resource for quantum information processing. While its certification is well-established in finite-d…
Variational-toolbox-based separability detection of multiqubit states
Jin-Min Liang, Shao-Ming Fei, Qiongyi He
Parametrized quantum circuits (PQCs) are crucial in variational quantum algorithms. While it is commonly believed that the optimal PQC is solely used to reproduce the target state,…

Chenghe Yu, Mingsheng Tian, Ningxin Kong +3
Exceptional points (EPs), arising in non-Hermitian systems, have garnered significant attention in recent years, enabling advancements in sensing, wave manipulation, and mode selec…
Uncertainty relations between quantum Fisher information and entanglement monotones
Shaowei Du, Shuheng Liu, Matteo Fadel +2
Entanglement is widely regarded as an essential resource for a number of tasks and can in some cases be quantified by figures of merit related to those tasks. In quantum metrology,…
