WitrynaMixed quantum stated can be represented by Hermitian tensors. A rank-1 Hermitian tensor must have form [v1;v2; ;vm] h:= v1 v2 vm v1 v2 vm: Every Hermitian tensor is a sum of rank-1 Hermitian tensors. The smallest such length is called Hermitian rank of H, denoted by hrank(H). The following topics are studied in the work: The Hermitian … WitrynaIn quantum mechanics, the expectation value is the probabilistic expected value of the result (measurement) of an experiment. It can be thought of as an average of all the possible outcomes of a measurement as weighted by their likelihood, and as such it is not the most probable value of a measurement; indeed the expectation value may have … WitrynaHermitian tensors are generalizations of Hermitian matrices, but they have very different properties.
