Bounds on Quantum Multiple-Parameter Estimation with Gaussian State
Yang Gao, Hwang Lee
We investigate the quantum Cramer-Rao bounds on the joint multiple-parameter estimation with the Gaussian state as a probe. We derive the explicit right logarithmic derivative and…

Optimal Estimation of a Classical Force with a Damped Oscillator in the non-Markovian Bath
Yang Gao, Hwang Lee, Yong Lei Jia
We solve the optimal quantum limit of probing a classical force exactly by a damped oscillator initially prepared in the factorized squeezed state. The memory effects of the therma…
