摘要：
We studied the statistical measures of covariance and correlation coefficient for noncommuting observables of quantum angular momentum and spin. Perfect correlation or anticorrelation is achievable for SU(2) atomic or spin coherent states, and the maximally entangled states of a composite spin-one system. We prove that these are the only states that minimize the generalized Heisenberg uncertainty principle for spin-one. (C) 1999 Elsevier Science B.V. All rights reserved.
