Fast escape of a quantum walker from an integrated photonic maze

2016 · Nature Communications

Escaping from a complex maze, by exploring different paths with several decision-making branches in order to reach the exit, has always been a very challenging and fascinating task. Wave field and quantum objects may explore …

Quantum spatial search in three-dimensional waveguide arrays

2021 · arXiv (Cornell University)

Continuous-time quantum walks (CTQW) have shown the capability to perform efficiently the spatial search of a marked site on many kinds of graphs. However, most of such graphs are hard to realize in an experimental …
