Journal Club title: Superposition of temporal orders

Abstract:

I'll review some recent papers on different topics relating temporal order and causality, on one hand, with quantum mechanics on the other. In particular, I'll review the idea of using superpositions of temporal orders for computational advantage [1], and a recent implementation of such a procedure in optical interferometers [2]. If time allows, I'll also discuss a couple of new results about how quantum systems may behave differently from classical systems with respect to determination of causal effects [3,4]. I'll end with the usual round-up of new results of interest to the group.
