Interference-induced state engineering and Hamiltonian control for noisy collective-spin metrology
Le Bin Ho, Vu Xuan Tung Duong, Nozomu Takahashi +1
Interference provides a fundamental mechanism for generating and manipulating entanglement in many-body quantum systems. Here, we develop an interference framework in which the non…

Trade-off relation between integrated metrological gain and local dissipation in magnetic-field sensing by quantum spin ensemble
Nozomu Takahashi, Le Bin Ho, Hiroaki Matsueda
Quantum metrology plays a central role in precision sensing, where quantum enhancement of detection performance is crucial for both fundamental studies and practical applications.…
