Correlations in few two-component quantum walkers on a tilted lattice

Quantum walk of two non-interacting particles on a 2D lattice

“…Jiao et al proposed a true 2D quantum walk with associated photons on a triangular photonic lattice, which can be mapped to a state space of up to 37 × 37 dimensions [9]. In the case of non-interacting systems, Sarkar et al [10] considered the simplest case where two indistinguishable non-interacting walkers on an inclined optical lattice interact with walkers from different components. Furthermore, Feng and Pang [11] analyzed the discrete time quantum walk of non-interacting multi-particle system in a 1D infinite lattice, and discussed the effects of entanglement and exchange symmetry on the particle position distribution during the quantum walk.…”
