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…
