The formulation of the no-cloning theorem in the framework of phase-space noncommutative (NC) quantum mechanics (QM) is examined, and its implications for the computation of quantum cloning probabilities and teleportation fidelity are investigated through the Weyl–Wigner formulation of QM. The principles of QM re-edited in terms of a deformed Heisenberg–Weyl algebra are shown to provide a covariant formulation for the quantum fidelity, through which the results from the no-cloning theorem for… 
Generalized phase-space description of nonlinear Hamiltonian systems and Harper-like dynamics
Abstract Phase-space features of the Wigner flow for generic 1-dim systems with Hamiltonian, HW (q, p), constrained by the ∂2HW /∂q∂p = 0 condition are analytically obtained in terms of Wigner
Spin‐Spacetime Censorship
Quantum entanglement and relativistic causality are key concepts in theoretical works seeking to unify quantum mechanics and gravity. In this article, a gedanken experiment that couples the spin to
Heat flow and noncommutative quantum mechanics in phase-space
In this work, we investigate the heat flow of two interacting quantum systems on the perspective of noncommutativity phase-space effects and show that by controlling the new constants introduced in


Coherent quantum squeezing due to the phase space noncommutativity
The effects of general noncommutativity of operators on producing deformed coherent squeezed states is examined in phase space. A two-dimensional noncommutative (NC) quantum system supported by a
Noncommutative Gravitational Quantum Well
We study noncommutative geometry at the quantum mechanics level by means of a model where noncommutativity of both configuration and momentum spaces is considered. We analyze how this model affects
The ⋆-value equation and Wigner distributions in noncommutative Heisenberg algebras
We consider the quantum mechanical equivalence of the Seiberg-Witten map in the context of the Weyl-Wigner-Groenewold-Moyal phase-space formalism in order to construct a quantum mechanics over
Phase-space noncommutative formulation of Ozawa’s uncertainty principle
Ozawa's measurement-disturbance relation is generalized to a phase-space noncommutative extension of quantum mechanics. It is shown that the measurement-disturbance relations have additional terms
Different operational meanings of continuous variable Gaussian entanglement criteria and Bell inequalities
Entanglement, one of the most intriguing aspects of quantum mechanics, marks itself into different features of quantum states. For this reason different criteria can be used for verifying
