Phys. Rev. A 69, 052112 (2004) [5 pages]Quantum phase space points for Wigner functions in finite-dimensional spacesReceived 6 December 2003; published 20 May 2004 We introduce quantum states associated with single phase space points in the Wigner formalism for finite-dimensional spaces. We consider both continuous and discrete Wigner functions. This analysis provides a procedure for a direct practical observation of the Wigner functions for states and transformations without inversion formulas. © 2004 The American Physical Society URL:
