Nonlocality of channels under decoherence.

Bell nonlocality asserts that correlations in quantum states cannot always be explained by hidden variables assuming local realism. While being extensively studied in the context of quantum states, the study of nonlocality for quantum channels has only recently garnered attention. A particularly relevant case concerns nonlocality of channels in realistic setups, where decoherence affects the ability to perform nonlocal protocols. In this talk we address the following questions: how to identify nonlocal properties of bipartite channels, and how do these properties change under decoherence?
