Abstract

By adding an extra Hilbert space to Hadamard Quantum Walk on Cycles (QWC), we presented a new type of QWCs called M\"obius Quantum Walk (MQW). The new space configuration enables the particle to rotate around the axis of movement. We defined factor α\alpha as the M\"obius factor which is number of rotations per cycle. So by α=0\alpha=0 we have normal QWC, while α0\alpha \neq 0 defines new type of QWC (namely M\"obius Quantum Walk). Specially α=12\alpha = \frac{1}{2} defines a structure similar to M\"obius strip. We analytically investigated this new type of QW and found that by tuning the parameter α\alpha we can reach uniform distribution for any number of nodes, while it is impossible for QWC. The effects of α\alpha on limiting distribution have been investigated and an explicit formula for non-uniform cases has been derived as well.
