Comparing the quantum switch and its simulations with energetically constrained operations

Quantum mechanics allows processes to be superposed, leading to a genuinely quantum lack of causal structure. For example, the process known as the quantum switch applies two operations A and B in a superposition of the two possible orders, A before B and B before A. Experimental implementations of...
