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…
On dynamical stability of composite quantum particles: when entanglement is enough and when interaction is needed
Zakarya Lasmar, Adam S. Sajna, Su-Yong Lee +1
We consider an evolution of two elementary quantum particles and ask the question: under what conditions such a system behaves as a single object? It is obvious that if the attract…
Disproving hidden variable models with spin magnitude conservation
Pawel Kurzynski, Wieslaw Laskowski, Adrian Kolodziejski +3
The squares of the three components of the spin-s operators sum up to . However, a similar relation is rarely satisfied by the set of possible spin projections onto mutuall…
Monogamy of particle statistics in tripartite systems simulating bosons and fermions
Marcin Karczewski, Dagomir Kaszlikowski, Pawel Kurzynski
In the quantum world correlations can take form of entanglement which is known to be monogamous. In this work we show that another type of correlations, indistinguishability, is al…
From contextuality of a single photon to realism of an electromagnetic wave
Marcin Markiewicz, Dagomir Kaszlikowski, Pawel Kurzynski +1
Violations of Bell inequalities have been an incontestable indicator of non-classicality since the seminal paper by John Bell. However, recent claims of Bell inequalities violation…
