Weighted Bures Length Uncovers Quantum State Sensitivity
Pawel Kurzynski
The unitarity of quantum evolutions implies that the overlap between two initial states does not change in time. This property is commonly believed to explain the lack of state sen…

Simulations of quantum nonlocality with local negative bits
Kelvin Onggadinata, Pawel Kurzynski, Dagomir Kaszlikowski
We propose a simple simulation of nonlocal quantum correlations among qubits using a local hidden variable source with a positive probability distribution, given that each the…

On Quantum Semipermeable Barriers: Investigating Maxwell's Demon Toolbox
Andrzej Grudka, Pawel Kurzynski, Antoni Wojcik
We study quantum Maxwell's demon in a discrete space-time setup. We consider a collection of particles hopping on a one-dimensional chain and a semipermeable barrier that allows th…
