Revisiting quantum walk advantages: A mean hitting time perspective
Jan Wójcik
The mean squared displacement has been widely used as the primary metric for comparing quantum and classical random walks, with quantum walks showing quadratic scaling versus linea…

Quantum Walks in Weak Stochastic Gauge Fields
Jan Wójcik
The behaviour of random quantum walks is known to be diffusive. Here we study discrete time quantum walks in weak stochastic gauge fields. In the case of position and spin dependen…
