Decomposition of split-step quantum walks for simulating Majorana modes and edge states (1703.05938v2)
Published 17 Mar 2017 in quant-ph and cond-mat.other
Abstract: We construct a decomposition procedure for converting split-step quantum walks into ordinary quantum walks with alternating coins, and we show that this decomposition enables a feasible linear optical realization of split-step quantum walks by eliminating quantum-control requirements. As salient applications, we show how our scheme will simulate Majorana modes and edge states.
