Infinite reduction in absorbing time in quantum walks over classical ones
Shuva Mondal, Amrita Mandal, Ujjwal Sen
We study the absorption time and spreading rate of the discrete-time quantum walk propagating on a line in the presence or absence of an absorber. We analytically establish that in…

Stronger resilience to disorder in 2D quantum walks than in 1D
Amrita Mandal, Ujjwal Sen
We study the response of spreading behavior, of two-dimensional discrete-time quantum walks, to glassy disorder in the jump length. We consider different discrete probability distr…
