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…

State tomography for two qubits using reduced densities
D. Petz, K. M. Hangos, A. Szanto +1
The optimal state determination (or tomography) is studied for a composite system of two qubits when measurements can be performed on one of the qubits and interactions of the two…

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…
