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

Review of student difficulties in upper-level quantum mechanics
Physical Review Special Topics. Physics Education Research, 2015 [This paper is part of the Focused Collection on Upper Division Physics Courses.] Learning advanced physics, in general, is challenging not only due to the increased mathematical sophistication but also because one must continue to build on all of the ...

Nuclear Physics B, 2015 We consider the multiple M2-branes wrapped on a compact Riemann surface and study the arising quantum mechanics by taking the limit where the size of the Riemann surface goes to zero.

Journal 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 ...

Quantum–Classical Mechanics and the Franck–Condon Principle
Computer 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.

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

Why the future cannot be open in the quantum world
Principia: 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.

Indistinguishability and Counting: Teaching the role of different interpretations in Quantum Mechanics [PDF]
Revista Brasileira de Ensino de Física, 2021 The theme of indistinguishability in the context of Quantum Mechanics as opposed to a distinguishability in the context of Classical Mechanics has been treated for almost a century in terms of an essential difference between the way of counting in ...

Quantum Inequalities in Quantum Mechanics [PDF]
Annales 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.

Renormalons in quantum mechanics [PDF]
Journal of High Energy Physics, 2019 Abstract We present a nonrelativistic one-particle quantum mechanics whose perturbative S-matrix exhibits a renormalon divergence that we explicitely compute. The potential of our model is the sum of the 2d Dirac δ-potential — known to require renormalization — and a 1d Dirac δ-potential tilted at an angle.
