Semi-device-independent certification of indefinite causal order

Semi-device-independent certification of indefinite causal order

When transforming pairs of independent quantum operations according to the fundamental rules of quantum theory, an intriguing phenomenon emerges: some such higher-order operations may act on the input operations in an indefinite causal order. Recently, the formalism of process matrices has been deve...
