SU(N)-symmetric quasi-probability distribution functions
Todd Tilma, Kae Nemoto · Journal of Physics A Mathematical and Theoretical · 2011
We present a set of N -dimensional functions, based on generalized SU ( N )-symmetric coherent states, that represent finite-dimensional Wigner, Q- and P-functions. We then show the fundamental properties of these functions and discuss their usefulness for analyzing N -dimensional pure and mixed quantum states.
