Article entitled "SIC-POVM and probability representation of quantum mechanics" has appeared in J. Russ. Laser Res.

This is to inform you that our article entitled "Symmetric informationally complete positive operator valued measure and probability representation of quantum mechanics" by Vladimir I. Man'ko and me has been published in Journal of Russian Laser Research 31(3), 211-231 (2010) <<link>>

Abstract

Symmetric informationally complete positive operator valued measures (SIC-POVMs) are studied within the framework of the probability representation of quantum mechanics. A SIC-POVM is shown to be a special case of the probability representation. The problem of SIC-POVM existence is formulated in terms of symbols of operators associated with a star-product quantization scheme. We show that SIC-POVMs (if they do exist) must obey general rules of the star product, and, starting from this fact, we derive new relations on SIC-projectors. The case of qubits is considered in detail, in particular, the relation between the SIC probability representation and other probability representations is established, the connection with mutually unbiased bases is discussed, and comments on the Lie algebraic structure of SIC-POVMs are presented.

Your comments are kindly welcome!
