Dynamical parameter estimation using realistic photodetection [PDF]

, 2004
We investigate the effect of imperfections in realistic detectors upon the problem of quantum state and parameter estimation by continuous monitoring of an open quantum system.

Dynamic nested sampling: an improved algorithm for parameter estimation and evidence calculation [PDF]

Statistics and computing, 2017
We introduce dynamic nested sampling: a generalisation of the nested sampling algorithm in which the number of “live points” varies to allocate samples more efficiently.

Frequentist and Bayesian Quantum Phase Estimation

Entropy, 2018
Frequentist and Bayesian phase estimation strategies lead to conceptually different results on the state of knowledge about the true value of an unknown parameter.

Mixed state Pauli channel parameter estimation

, 2012
The accuracy of any physical scheme used to estimate the parameter describing the strength of a single qubit Pauli channel can be quantified using standard techniques from quantum estimation theory.

Robust Parameter Estimation for a Class of Nonlinear System With EM Algorithm

IEEE Access, 2020
This paper is concerned with the robust parameter estimation for linear parameter varying (LPV) finite impulse response (FIR) model. The practical process data are typically polluted by outliers and conventional parameter estimation methods may fail to ...

Parameter estimation in nonlinear stochastic differential equations

, 2000
We discuss the problem of parameter estimation in nonlinear stochastic differential equations based on sampled time series. A central message from the theory of integrating stochastic differential equations is that there exists in general two time scales,

Frequency Tracking and Parameter Estimation for Robust Quantum State-Estimation

, 2011
In this paper we consider the problem of tracking the state of a quantum system via a continuous measurement. If the system Hamiltonian is known precisely, this merely requires integrating the appropriate stochastic master equation. However, even a small
