Multiparameter quantum estimation with a uniformly accelerated Unruh-DeWitt detector
Shoukang Chang, Yashu Yang, Wei Ye +6
The uniformly accelerated Unruh-DeWitt detector serves as a fundamental model in relativistic quantum metrology. While previous studies have mainly concentrated on single-parameter…
A note on Schmidt-number witnesses based on symmetric measurements
Xiao-Qian Mu, Hao-Fan Wang, Shao-Ming Fei
The Schmidt number is an important kind of characterization of quantum entanglement. Quantum states with higher Schmidt numbers demonstrate significant advantages in various quantu…
Genuine Multipartite Entanglement Measure Based on -concurrence
Ke-Ke Wang, Zhi-Wei Wei, Shao-Ming Fei
Quantifying genuine entanglement is a crucial task in quantum information theory. Based on the geometric mean of bipartite -concurrences among all bipartitions, we present a cla…
Estimating the Schmidt numbers of quantum states via symmetric measurements
Hao-Fan Wang, Shao-Ming Fei
The Schmidt numbers quantify the entanglement degree of quantum states. Quantum states with high Schmidt numbers provide a larger advantage in various quantum information processin…
Detectors for local discrimination of sets of generalized Bell states
Cai-Hong Wang, Jiang-Tao Yuan, Ying-Hui Yang +3
A fundamental problem in quantum information processing is the discrimination among a set of orthogonal quantum states of a composite system under local operations and classical co…
Symmetric measurement-induced lower bounds of concurrence
Hao-Fan Wang, Shao-Ming Fei
We provide a class of lower bounds for concurrence based on symmetric measurements. We show that our lower bounds estimate the quantum entanglement better than some existing lower…
