Trapping of continuous-time quantum walks on Erdös-Rényi graphs

We consider the coherent exciton transport, modeled by quantum walk, on random graphs. ► We introduce a random distribution of traps and measure the survival probability. ► We investigate the role of trap concentration and dilution degree of substrate. ► We compare results with those pertaining to a classical walk (incoherent propagation). ► We highlight genuine quantum-mechanical effects.
