Contextuality in Classical Physics and Its Impact on the Foundations of Quantum Mechanics [PDF]

Entropy, 2021
It is shown that the hallmark quantum phenomenon of contextuality is present in classical statistical mechanics (CSM). It is first shown that the occurrence of contextuality is equivalent to there being observables that can differentiate between pure and

Foundations of Quantum Mechanics

Encyclopedia, 2022
Quantum mechanics is a mathematical formalism that models the dynamics of physical objects. It deals with the elementary constituents of matter (atoms, subatomic and elementary particles) and of radiation.

Conservation laws and the foundations of quantum mechanics. [PDF]

Proc Natl Acad Sci U S A, 2023
In a recent paper, [Y. Aharonov, S. Popescu, D. Rohrlich, Proc. Natl. Acad. Sci. U.S.A. 118 e1921529118 (2021)], it was argued that while the standard definition of conservation laws in quantum mechanics, which is of a statistical character, is perfectly valid, it misses essential features of nature and ...

Foundations of the Quaternion Quantum Mechanics [PDF]

Entropy, 2020
We show that quaternion quantum mechanics has well-founded mathematical roots and can be derived from the model of the elastic continuum by French mathematician Augustin Cauchy, i.e., it can be regarded as representing the physical reality of elastic ...

Testing quantum foundations with quantum computers

Physical Review Research, 2022
We present two complementary viewpoints for combining quantum computers and the foundations of quantum mechanics. On the one hand, ideal devices can be used as test beds for experimental tests of the foundations of quantum mechanics: We provide ...

Delayed-Choice Phenomena in the Projection Evolution Model [PDF]

Entropy
In the Schrödinger evolution of a quantum state, time enters as a real parameter representing the coordinate. In a more consistent approach, time should be defined as a quantum observable, with the evolution taking place in a four-dimensional spacetime ...

Entropic Dynamics Approach to Quantum Electrodynamics [PDF]

Entropy
Entropic Dynamics (ED) is a framework that allows one to derive quantum theory as a Hamilton–Killing flow on the cotangent bundle of a statistical manifold.

Entropic Dynamics Approach to Relational Quantum Mechanics [PDF]

Entropy
The general framework of Entropic Dynamics (ED) is used to construct non-relativistic models of relational Quantum Mechanics from well-known inference principles—probability, entropy and information geometry.

Epistemic Horizons and the Foundations of Quantum Mechanics [PDF]

Foundations of Physics, 2018
In-principle restrictions on the amount of information that can be gathered about a system have been proposed as a foundational principle in several recent reconstructions of the formalism of quantum mechanics. However, it seems unclear precisely why one should be thus restricted.
