Quantum key distribution by phase flipping of coherent states of light
G. A. Barbosa, J. van de Graaf, P. Mateus +1
In this paper we present quantum key distribution protocol that, instead of single qubits, uses mesoscopic coherent states of light to encode bit values of a randomly g…

Boltzmann-Gibbs states in topological quantum walks and associated many-body systems: Fidelity and Uhlmann parallel transport analysis of Phase Transitions
Bruno Mera, Chrysoula Vlachou, Nikola Paunković +1
We perform the fidelity analysis for Boltzmann-Gibbs-like states in order to investigate whether the topological order of 1D fermionic systems at zero temperature is maintained at…

Gravity-Matter Entanglement in Regge Quantum Gravity
Nikola Paunković, Marko Vojinović
We argue that Hartle-Hawking states in the Regge quantum gravity model generically contain non-trivial entanglement between gravity and matter fields. Generic impossibility to talk…
