Nonclassical oscillations in pre- and post-selected quantum walks
Xiaoxiao Chen, Zhe Meng, Jian Li +4
Quantum walks are counterparts of classical random walks. They spread faster, which can be exploited in information processing tasks, and constitute a versatile simulation platform…

From classical to quantum walk via erasure of which-way information
Mikolaj Lewandowski, Tomasz Kopyciuk, Pawel Kurzynski
Decoherence transforms a ballistic quantum walk into a diffusive classical random walk. After each step the environment measures the particle's path and the outside world gets to k…
