Directional correlations in quantum walks with two particles
Original language description
Quantum walks on a line with a single particle possess a classical analogue. Involving more walkers opens up the possibility of studying collective quantum effects, such as many-particle correlations. In this context, entangled initial states and the indistinguishability of the particles play a role. We consider the directional correlations between two particles performing a quantum walk on a line. For non-interacting particles, we find analytic asymptotic expressions and give the limits of directionalcorrelations. We show that by introducing ?-interaction between the particles, one can exceed the limits for non-interacting particles.
