Abstract

Proving the additivity of the classical capacity of quantum channels is a major open problem in quantum information.  This problem is related to the multiplicativity of certain norms with respect to the tensor product.  These problems are introduced and some approached to resolving them are discussed.  Several special cases that have been solved are also mentioned.
