Projection Theorem for Discrete-Time Quantum Walks
Václav Potoček
We make and generalize the observation that summing of probability amplitudes of a discrete-time quantum walk over partitions of the walking graph consistent with the step operator…

Vorticity and the birth of optical vortices
Václav Potoček, Yu Wang, Stephen M. Barnett
We exploit the vorticity, familiar from fluid mechanics and the theory of superfluids, as a tool to track the birth and subsequent development of optical vortices at a spiral phase…

Symmetries in discrete time quantum walks on Cayley graphs
Václav Potoček
We address the question of symmetries of an important type of quantum walks. We introduce all the necessary definitions and provide a rigorous formulation of the problem. Using a t…
