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…

Deciding universality of quantum gates
Gabor Ivanyos
We say that collection of -qudit gates is universal if there exists such that for every every -qudit unitary operation can be approximated with arbitr…
