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…
Non-Gaussian Entanglement Hierarchy Based on the Schmidt Number
Jiajie Guo, Shuheng Liu, Matteo Fadel +1
Non-Gaussian entanglement is a promising resource in various quantum tasks. A recently defined class identifies entanglement that cannot be generated by applying Gaussian operation…
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,…
Witnessing genuine multipartite entanglement in phase space with controlled Gaussian unitaries
Lin Htoo Zaw, Jiajie Guo, Qiongyi He +2
Many existing genuine multipartite entanglement (GME) witnesses for continuous-variable (CV) quantum systems typically rely on quadrature measurements, which are challenging to imp…
Sufficient Wigner Negativity Implies Genuine Multipartite Entanglement
Lin Htoo Zaw, Jiajie Guo, Qiongyi He +2
Wigner negativity and genuine multipartite entanglement (GME) are key nonclassical resources that enable computational advantages and broader quantum-information tasks. In this wor…
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…
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,…
Characterizing resources for multiparameter estimation of SU(2) and SU(1,1) unitaries
Shaowei Du, Shuheng Liu, Frank E. S. Steinhoff +1
We analyze the task of estimating a multi-parameter unitary belonging to the or groups, in a two-bosonic-mode scenario and investigate the scaling of the precisio…
