Quantum channels of the Einstein-Podolski-Rosen kind
arXiv:quant-ph/9901027
Abstract
Assume the quantum state of a bipartite system is known. The result of local von Neumann measurements can be described by maps from one subsystem to the other one. Main properties of these antilinear ''EPR-channel'' maps are shortly discussed. Talk in honour of Jan Lopuszanski.
