Pre- and post-selection paradoxes in quantum walks
Tomasz Kopyciuk, Mikolaj Lewandowski, Pawel Kurzynski
Many features of single-partite quantum walks can be simulated by classical waves. However, it was recently experimentally shown that some temporal sequences of measurements on a q…

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…
