Decomposition of split-step quantum walks for simulating Majorana modes and edge states

Quantum Physics 2017-05-31 v2 Other Condensed Matter

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.
