Abstract

In distributed quantum information processing, the parties are often limited to performing local operations and classical communication (LOCC). The class of LOCC is notoriously difficult to analyze, and typically one considers the larger class of so-called separable (SEP) operations, which has a nicer mathematical structure. Finding separable but non-LOCC maps is a challenging endeavor, with most known examples involving the task of state discrimination. In this talk, I will describe an approach for constructing SEP but non-LOCC channels based on the resource theory of quantum coherence. This further highlights the value of studying general resource theories within quantum information theory. This is joint work with Ludovico Lami.
