For example, Konno [10] proved that, for localized initial states, a discrete-time quantum walk on the line with a finite number of internal degrees of freedom usually has a limit distribution with scaling speed n, which is far from being Gaussian.
Recently, with the help of quantum Bernoulli noise, Wang and Ye [13] have constructed a discrete-time quantum walk with infinitely many internal degrees of freedom, which we call the QBN-based walk below.
It has been shown [13] that, for some localized initial states, the QBN-based walk has a Gaussian limit distribution with scaling speed [square root of (n)], which is in striking contrast with the case of the usual discrete-time quantum walks with a finite number of internal degrees of freedom.
