For the purposes of quantum tomography the prior distribution over the state space should be non-informative or uniform. It is natural to identify unifor-mity with maximal symmetry. In the case of pure states such prior distribution is unique and it is determined by the requirement of unitary invariance [14]. Therefore the Haar measure ... gynecologist near statesboro ga
