LIV-Decoherence on Gravitational Cat States
Iarley P. Lobo, Kelvin Sampaio, Gislaine Varão +2
Inspired by approaches based on the stochastic generalized uncertainty principle, we propose a Lindblad equation derived from the quantization of a stochastic modified dispersion r…
Induced electric dipole moment coupling in Dirac equation
K. Bakke
We introduce a nonminimal coupling into the Dirac equation as a model of describing the interaction of a Dirac neutral particle with an induced electric dipole moment with magnetic…
Coherence and Entanglement in a Non-commutative Spacetime
Iarley P. Lobo, Gislaine Varão, Giulia Gubitosi +2
We investigate the emergence of quantum coherence and quantum correlations in a two-particle system with deformed symmetries arising from the quantum nature of spacetime. We demons…
Accelerating Feedback-Based Quantum Algorithms through Time Rescaling
L. A. M. Rattighieri, G. E. L. Pexe, B. L. Bernado +1
This work investigates the impact of time rescaling on the performance of Feedback Quantum Algorithms (FQA) and their variant for optimization tasks, FALQON. We introduce TR-FQA an…
Single-Qudit Quantum Neural Networks for Multiclass Classification
Leandro C. Souza, Renato Portugal
This paper proposes a single-qudit quantum neural network for multiclass classification, by using the enhanced representational capacity of high-dimensional qudit states. Our desig…
Entangled states from simple quantum graphs
Alison A. Silva, D. Bazeia, Fabiano M. Andrade
Entanglement is a fundamental resource for many applications in quantum information processing. Here, we investigate how quantum transport in simple quantum graphs, modeled as cont…
