Any other use requires prior permission of the author and the American Institute of Physics., States on the coupled quantum system M-n(C)circle times M-n(C) whose restrictions to each subsystem are the normalized traces are called marginal tracial states. We investigate extremal marginal tracial states and compute their maximal rank. Diagonal marginal tracial states are also considered., Article, JOURNAL OF MATHEMATICAL PHYSICS. 51(9):092101 (2010)},
