Wigner Distributions for Qudits : Two Approaches
  KTH/Nordita/SU seminar in Theoretical Physics [before December 2013]

Wednesday 21 March 2007
from 11:00 to 12:00
at FA31
Speaker : Subhash Chaturvedi (Hyderabad)
Abstract : Two approaches to setting up Wigner distributions for finite state quantum systems are outlined. While the first is group theoretic in nature and works for all finite groups of odd order ( abelian as well as non abelian), the second, inspired by Dirac's work on functions of non commuting obseravables, entails finding a specific square root of a certain Hadamard matrix and works in all dimensions.
