The Choi-Jamio lkowski Isomorphism is a remarkable result in the field of open quantum systems and quantum information theory establishing the correspon-
dence between linear maps in operator algebras and bipartite operators in the cor-responding Hilbert spaces. Nearly five decades ago it was established that positive maps correspond to block-positive operators [1] and completely positive maps cor-respond to positive operators [2]. The workshop aims to celebrate this fundamental result and is devoted to new frontiers in the research in open quantum systems,entanglement and quantum information theory.
