Does The Uncertainty Relation Determine The Quantum State?

arXiv:quant-ph/0604044 · doi:10.1016/j.physleta.2006.04.116

Abstract

The example of nonpositive trace-class Hermitian operator for which Robertson-Schroedinger uncertainty relation is fulfilled is presented. The partial scaling criterion of separability of multimode continuous variable system is discussed in the context of using nonpositive maps of density matrices.
