Covertness as a resource constraint in quantum target sensing
Yu Yang, Fengyu Guan, Shiping Guo +3
Quantum covert target sensing aims to detect low-reflectivity targets embedded in the thermal environment while avoiding discovery by an adversary. This covertness requirement cons…
Floquet quantum multiparameter estimation with periodic-driving-induced topological phase transition
Yu Yang, Yuyang Tang, Pei Zhang +1
Periodically driven systems provide a powerful platform for quantum multiparameter estimation. Constructing a static effective Hamiltonian in a proper rotating frame is commonly em…
Distinct Critical Scaling of Quantum Fisher Information in a Quantum Rabi Triangle System
Yuyang Tang, Yu Yang, Min An +1
Critical properties of a quantum system are recognized as valuable resources for quantum metrology. In this work, we investigate the criticality-enhanced sensing in a quantum Rabi…
Quantum multiparameter estimation enhanced by a topological phase transition
Yu Yang, Haidong Yuan, Fuli Li
In quantum multiparameter estimation, multiple to-be-estimated parameters are encoded in a quantum dynamics system by a unitary evolution. As the parameters vary, the system may un…
Witnessing Quantum Incompatibility Structures in High-Dimensional Multimeasurement Systems
Xiaolin Zhang, Rui Qu, Zehong Chang +6
Quantum incompatibility, referred as the phenomenon that some quantum measurements cannot be performed simultaneously, is necessary for various quantum information processing tasks…
