Optimal feedback scheme and universal time scaling for Hamiltonian parameter estimation
H Yuan, CHF Fung - Physical review letters, 2015 - APS
Time is a valuable resource and it is expected that a longer time period should lead to better
precision in Hamiltonian parameter estimation. However, recent studies in quantum …
