Tensorial quantum mechanics [PDF]

open access: yesScientific Reports
In July 1925, exactly one century ago, Werner Heisenberg created Quantum Mechanics (QM) as an invariant-operational formalism by taking as a standpoint the intensive patterns that had been already observed by experimentalists in the lab.

Algebraic Quantum Mechanics and Pregeometry [PDF]

open access: yes, 2006
We discuss the relation between the q-number approach to quantum mechanics suggested by Dirac and the notion of "pregeometry" introduced by Wheeler. By associating the q-numbers with the elements of an algebra and regarding the primitive idempotents as ...

Homological quantum mechanics

open access: yesJournal of High Energy Physics
We provide a formulation of quantum mechanics based on the cohomology of the Batalin-Vilkovisky (BV) algebra. Focusing on quantum-mechanical systems without gauge symmetry we introduce a homotopy retract from the chain complex of the harmonic oscillator ...

Quantum–Classical Mechanics and the Franck–Condon Principle

open access: yesComputer Sciences & Mathematics Forum, 2023
Quantum–classical mechanics and the Franck–Condon principle related to quantum mechanics are discussed as two alternative theoretical approaches to molecular optical spectroscopy.

QUANTUM COMPUTING [PDF]

open access: yesJournal of Engineering Science (Chişinău), 2021
The quantum computer, is a "supercomputer" that relies on the phenomena of quantum mechanics to perform operations on data. Object of suppositions, sometimes far- fetched, quantum mechanics gave birth to the quantum computer, a machine capable of ...

De novo design of novel spike glycoprotein inhibitors using

open access: yesPakistan Journal of Pharmaceutical Sciences, 2022
The pandemic COVID-19, caused by SARS-COV-2, has been a global concern and burden since April 2020 due to high contagiousness and pathogenesis. A great effort is being devoted to identify and investigate different druggable targets for SARS-COV-2 drug ...

Depicting qudit quantum mechanics and mutually unbiased qudit theories [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2014
We generalize the ZX calculus to quantum systems of dimension higher than two. The resulting calculus is sound and universal for quantum mechanics. We define the notion of a mutually unbiased qudit theory and study two particular instances of these ...

Quantum Inequalities in Quantum Mechanics [PDF]

open access: yesAnnales Henri Poincaré, 2005
We study a phenomenon occuring in various areas of quantum physics, in which an observable density (such as an energy density) which is classically pointwise nonnegative may assume arbitrarily negative expectation values after quantisation, even though the spatially integrated density remains nonnegative.

Why the future cannot be open in the quantum world

open access: yesPrincipia: An International Journal of Epistemology, 2022
In this study, I argue that the future is not open if quantum mechanics is complete. An open future means that the value observed when measuring a physical quantity in the future is not determined.

On tests of the quantum nature of gravitational interactions in presence of non-linear corrections to quantum mechanics [PDF]

open access: yesQuantum, 2023
When two particles interact primarily through gravity and follow the laws of quantum mechanics, the generation of entanglement is considered a hallmark of the quantum nature of the gravitational interaction.
