Application of Pontryagin's Maximum Principle to Quantum Metrology in Dissipative Systems
Chungwei Lin, Yanting Ma, Dries Sels
Optimal control theory, also known as Pontryagin's Maximum Principle, is applied to the quantum parameter estimation in the presence of decoherence. An efficient procedure is devis…
Quantum speed limit for the maximum coherent state under squeezed environment
Kang-ying Du, Ya-jie Ma, Shao-xiong Wu +1
The quantum speed limit time for quantum system under squeezed environment is studied. We consider two typical models, the damped Jaynes-Cummings model and the dephasing model. For…
Optimal Control for Quantum Metrology via Pontryagin's principle
Chungwei Lin, Yanting Ma, Dries Sels
Quantum metrology comprises a set of techniques and protocols that utilize quantum features for parameter estimation which can in principle outperform any procedure based on classi…
Stochastic optimal control formalism for an open quantum system
Chungwei Lin, Dries Sels, Yanting Ma +1
A stochastic procedure is developed which allows one to express Pontryagin's maximum principle for dissipative quantum system solely in terms of stochastic wave functions. Time-opt…
