Unitary Realizations of Synchronizing Automata in Quantum Systems
Jȩdrzej Stempin, Jan Wójcik, Gabriela Banaszak +4
We introduce a quantum analogue of a classical synchronizing automaton. In classical case the state of a system evolves according to a set of rules forming an alphabet, and sequenc…
In defense of temporal Tsirelson bound
Antoni Wójcik, Jan Wójcik
In a recent paper, Chatterjee et al. [Phys. Rev. Lett 135, 220202 (2025)] analyze and experimentally implement a specific unitary evolution of a simple quantum system. The authors…
Rabi transport and the other finite-size effects in one-dimensional discrete-time topological quantum walk
Andrzej Grudka, Marcin Karczewski, PaweÅ KurzyÅski +3
This paper investigates Rabi transport and finite-size effects in one-dimensional discrete-time topological quantum walks. We demonstrate the emergence of localized states at bound…
Simple explanation of apparent Bell nonlocality of unentangled photons
Antoni Wójcik, Jan Wójcik
Wang et al. [Science Advances, 1 Aug 2025 Vol 11, Issue 31] recently reported an experiment that they interpret as demonstrating a violation of Bell's inequality using unentangled…
Sending absolutely maximally entangled states through noisy quantum channels
Maria Stawska, Jan Wójcik, Andrzej Grudka +1
Absolutely maximally entangled states are quantum states that exhibit maximal entanglement across any bipartition, making them valuable for applications. This study investigates th…
Quantum Resetting Protocols Based on Synchronizing Words
JÄdrzej Stempin, Jan Wójcik, Andrzej Grudka +3
Resetting a system's state plays a fundamental role in physics, engineering, computer science, and many other fields. Here we focus on a method originally proposed in automata theo…
