摘要：
Parallel to antiparallel transformation of Bloch vectors on any large circle was studied to determine the antiparallel spin characteristics. The vectors constitute the largest set for which the parallel states are transformed to their corresponding antiparallel states. But if the antiparallel states span the whole Gilbert space, then a probabilistic exact parallel to antiparallel transformation ceases to exist. Inferences also indicate that information about the arbitrary vectors are available more from their corresponding antiparallel states than from the parallel ones.
