Transition in Splitting Probabilities of Quantum Walks
Prashant Singh · David A. Kessler · Eli Barkai
Abstract
Author(s): Prashant Singh, David A. Kessler, and Eli Barkai<br/><p>We investigate the splitting probability of a monitored continuous-time quantum walk with two targets and show that, in stark contrast to a classical random walk, it exhibits a nonanalytic, phase-transition-like behavior controlled by the sampling time at the targets. For large systems and sampling …</p><br/>[Phys. Rev. Lett. 137, 090405] Published Fri Aug 28, 2026
