Single-photon implementation of an indefinite causal order
Lorenzo M. Procopio, University of Vienna
Investigating the role of causal order in quantum mechanics has recently revealed that the temporal distribution of events may not be a-priori well-defined in quantum theory. Although this has triggered a growing interest on the theoretical side, the existence of processes without a causal order is an experimental question. In this talk, I will present an optical implementation of an indefinite causal-order structure called quantum switch for two purposes; to execute an algorithm and to verify a causally non-separable process.
