| Figure 6. Entropy versus the number of steps of the walk up to T = 30 and initial state Φint1. The solid blue line represents the Shannon entropy of the quantum walk with position-dependent entangled coins (PDEC) and the dashed red line represents the case of position-independent entangled coins (PIEC). Entropy is lower for PDEC as compared to PIEC for different rotation angles except for θ = π/90. |
