Experiencing the communication advantage of the Indefinite Causal Orders

Abstract

Many recent studies deal with the Superposition of Causal Orders, a quantum operation with promising advantages in both communication or computing. To experience the advantages, there are several way of implementing it. In literature, most of the set-ups are photonic-based. Instead, our interest is witnessing the Superpositon of Causal Orders within a programmable technology, based on superconductors. To do that, we focus on a specific case of the subject operation, which could be useful for the future of quantum communication.
