SU(N)-symmetric quasi-probability distribution functions (1108.2075v2)
Published 10 Aug 2011 in quant-ph, math-ph, and math.MP
Abstract: We present a set of N-dimensional functions, based on generalized SU(N)-symmetric coherent states, that represent finite-dimensional Wigner functions, Q-functions, 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.
