Averaging in SU(2) open quantum random walk

doi:10.1088/1674-1056/23/3/030302

Abstract We study the average position and the symmetry of the distribution in the SU(2) open quantum random walk (OQRW). We show that the average position in the central limit theorem (CLT) is non-uniform compared with the average position in the non-CLT. The symmetry of distribution is shown to be even in the CLT.

Keywords: open quantum random walk central limit theorem average position SU(2) operator
