Measurements in the Lévy quantum walk
arXiv:0710.1320 · doi:10.1103/PhysRevA.76.054306
Abstract
We study the quantum walk subjected to measurements with a Lévy waiting-time distribution. We find that the system has a sub-ballistic behavior instead of a diffusive one. We obtain an analytical expression for the exponent of the power law of the variance as a function of the characteristic parameter of the Lévy distribution.
