Parameter estimation of quantum processes using convex optimization
Gábor Balló, Katalin M. Hangos
A convex optimization based method is proposed for quantum process tomography, in the case of known channel model structure, but unknown channel parameters. The main idea is to sel…

Point Estimation of States of Finite Quantum Systems
D. Petz, K. M. Hangos, A. Magyar
The estimation of the density matrix of a -level quantum system is studied when the parametrization is given by the real and imaginary part of the entries and they are estimated…

Comparison of some methods of quantum state estimation
Th. Baier, K. M. Hangos, A. Magyar +1
In the paper the Bayesian and the least squares methods of quantum state tomography are compared for a single qubit. The quality of the estimates are compared by computer simulatio…
