Exceptional sensitivity near the bistable transition point of a hybrid quantum system
Hanfeng Wang, Kurt Jacobs, Donald Fahey +3
Phase transitions can dramatically alter system dynamics, unlocking new behavior and improving performance. Exceptional points (EPs), where the eigenvalues and corresponding eigenv…
Heisenberg-limited continuous-variable distributed quantum metrology with arbitrary weights
Wenchao Ge, Kurt Jacobs
Distributed quantum metrology (DQM) enables the estimation of global functions of d distributed parameters beyond the capability of separable sensors. Continuous-variable DQM invol…
Cavity-enhanced solid-state nuclear spin gyroscope
Hanfeng Wang, Shuang Wu, Kurt Jacobs +3
Solid-state quantum sensors based on ensembles of nitrogen-vacancy (NV) centers in diamond have emerged as powerful tools for precise sensing applications. Nuclear spin sensors are…
Microwave single-photon detection using a hybrid spin-optomechanical quantum interface
Pratyush Anand, Ethan G. Arnault, Matthew E. Trusheim +2
Semiconductor single-photon detectors cannot be straightforwardly adapted for the microwave regime, primarily because microwave photons carry far less energy and thus require cryog…
