Effects of underlying topology on quantum state discrimination

open access: yesEuropean Physical Journal C: Particles and Fields
In this work, we show that quantum state discrimination can be modified due to a change in the underlying topology of a system. In particular, we explicitly demonstrate that the quantum state discrimination of systems with underlying discrete topology ...

Noncommutative scalar fields: Quantum symmetries and braided BV quantization [PDF]

open access: yesKragujevac Journal of Science
It is strongly believed that the fully consistent quantum gravity theory should lead to a quantum spacetime. The continuous description of spacetime in terms of differential manifolds is no longer adequate at the quantum gravity energies.

Statistical and entanglement entropy for black holes in quantum geometry

open access: yes, 2014
We analyze the relationship between entanglement (or geometric) entropy with statistical mechanical entropy of horizon degrees of freedom when described in the framework of isolated horizons in loop quantum gravity.

Quantum Information Processing in Human Cognition: Bridging Quantum Phenomena, Neural Dynamics, and Decision‐Making

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 6, June 2026.
ABSTRACT Recent advances at the intersection of quantum physics, neuroscience, and cognitive science have renewed interest in whether quantum phenomena and quantum‐inspired formalisms can inform models of human cognition and decision‐making. While classical neural and computational models explain many aspects of perception and behavior, they face ...

A quantum reduction to spherical symmetry in loop quantum gravity

open access: yesPhysics Letters B, 2015
Based on a recent purely geometric construction of observables for the spatial diffeomorphism constraint, we propose two distinct quantum reductions to spherical symmetry within full 3+1-dimensional loop quantum gravity.

Discrete Gravity Models and Loop Quantum Gravity: a Short Review

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2012
We review the relation between Loop Quantum Gravity on a fixed graph and discrete models of gravity. We compare Regge and twisted geometries, and discuss discrete actions based on twisted geometries and on the discretization of the Plebanski action.
