Quantum state estimation and large deviations [PDF]
, 2004 In this paper we propose a method to estimate the density matrix \rho of a d-level quantum system by measurements on the N-fold system. The scheme is based on covariant observables and representation theory of unitary groups and it extends previous ...

Secure State Estimation: Optimal Guarantees against Sensor Attacks in the Presence of Noise [PDF]
, 2015 Motivated by the need to secure cyber-physical systems against attacks, we consider the problem of estimating the state of a noisy linear dynamical system when a subset of sensors is arbitrarily corrupted by an adversary.

Invariant information and quantum state estimation [PDF]
, 2001 The invariant information introduced by Brukner and Zeilinger, Phys. Rev. Lett. 83, 3354 (1999), is reconsidered from the point of view of quantum state estimation. We show that it is directly related to the mean error of the standard reconstruction from

Fidelity-optimized quantum state estimation
New Journal of Physics, 2015 We describe an optimized, self-correcting procedure for the Bayesian inference of pure quantum states. By analyzing the history of measurement outcomes at each step, the procedure returns the most likely pure state, as well as the optimal basis for the ...
