Approaching the Limit in Multiparameter AC Magnetometry with Quantum Control
Takuya Isogawa, Zhiyao Hu, Ayumi Kanamoto +9
Simultaneously estimating multiple parameters at the ultimate limit is a central challenge in quantum metrology, often hindered by inherent incompatibilities in optimal estimation…
Optimal scheme for distributed quantum metrology
Zhiyao Hu, Allen Zang, Jianwei Wang +4
Optimal strategies for local quantum metrology -- including the preparation of optimal probe states, implementation of optimal control and measurement strategies, are well establis…
Entanglement-assisted multiparameter estimation with a solid-state quantum sensor
Takuya Isogawa, Guoqing Wang, Boning Li +5
Quantum multiparameter estimation promises to extend quantum advantage to the simultaneous high-precision measurements of multiple physical quantities. However, realizing this capa…
Relative entropy formulation of thermalization process in a Schwarzschild spacetime
Si-Wei Han, Zhichun Ouyang, Zhiyao Hu +1
We revisit the problem of the thermalization process in an entropic formulation for the Unruh-DeWitt (UDW) detector outside a Schwarzschild black hole. We derive the late-time dyna…
Control incompatibility in multiparameter quantum metrology
Zhiyao Hu, Shilin Wang, Linmu Qiao +6
In practical applications like quantum sensing and quantum imaging, there is often a necessity to estimate multiple parameters simultaneously. Although the ultimate precision limit…
Emulated nuclear spin gyroscope with NV centers in diamond
Guoqing Wang, Minh-Thi Nguyen, Dane W. deQuilettes +4
Nuclear spins in solid-state platforms are promising for building rotation sensors due to their long coherence times. Among these platforms, nitrogen-vacancy centers have attracted…
