Reexamination of the Kochen-Specker theorem: Relaxation of the completeness assumption
Kelvin Onggadinata, Dagomir Kaszlikowski, Pawel Kurzynski
The Kochen-Specker theorem states that exclusive and complete deterministic outcome assignments are impossible for certain sets of measurements, called Kochen-Specker (KS) sets. A…
Relative homotopy approach to topological phases in quantum walks
Andrzej Grudka, Marcin Karczewski, Pawel Kurzynski +2
Discrete-time quantum walks (DTQWs) provide a convenient platform for a realisation of many topological phases in noninteracting systems. They often offer more possibilities than s…
Complementarity in quantum walks
Andrzej Grudka, Pawel Kurzynski, Tomasz P. Polak +3
We study discrete-time quantum walks on -cycles with a position and coin-dependent phase-shift. Such a model simulates a dynamics of a quantum particle moving on a ring with an…
Qubit from the classical collision entropy
Kelvin Onggadinata, Pawel Kurzynski, Dagomir Kaszlikowski
An orthodox formulation of quantum mechanics relies on a set of postulates in Hilbert space supplemented with rules to connect it with classical mechanics such as quantisation tech…
