Complementary Decompositions and Unextendible Mutually Unbiased Bases
Andras Szanto
Unextendible sets of Mutually Unbiased Bases (MUBs) are examined from the point of view of complementary subalgebras. We show, that the linear span of less than factors of $M…
Conditional SIC-POVMs
D. Petz, L. Ruppert, A. Szanto
In this paper we examine a generalization of the symmetric informationally complete POVMs. SIC-POVMs are the optimal measurements for full quantum tomography, but if some parameter…
Complementarity and the algebraic structure of 4-level quantum systems
D. Petz, A. Szanto, M. Weiner
The history of complementary observables and mutual unbiased bases is reviewed. A characterization is given in terms of conditional entropy of subalgebras. The concept of complemen…
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…
