Experimental Predictions for Norm-Conserving Spontaneous Collapse

Entropy, 2023
Previous work has shown that nonlocal collapse in quantum mechanics can be described by a deterministic, non-unitary operator added to the standard Schrödinger equation.

On the Stochastic Mechanics Foundation of Quantum Mechanics

, 2021
Among the famous formulations of quantum mechanics, the stochastic picture developed since the middle of the last century remains one of the less known ones.

Planck-Scale Soccer-Ball Problem: A Case of Mistaken Identity

Entropy, 2017
Over the last decade, it has been found that nonlinear laws of composition of momenta are predicted by some alternative approaches to “real” 4D quantum gravity, and by all formulations of dimensionally-reduced (3D) quantum gravity coupled to matter.

Uncertainty Relation for Errors Focusing on General POVM Measurements with an Example of Two-State Quantum Systems

Entropy, 2020
A novel uncertainty relation for errors of general quantum measurement is presented. The new relation, which is presented in geometric terms for maps representing measurement, is completely operational and can be related directly to tangible measurement ...

Identical Quantum Particles and Weak Discernibility [PDF]

, 2007
We examine a recent argument that ``identical'' quantum particles with an anti-symmetric state (fermions) are weakly discernible objects, just like irreflexively related ordinary objects in situations with perfect symmetry (Black's spheres, for example).

QUANTUM THEOLOGY BEYOND COPENHAGEN: TAKING FUNDAMENTALISM LITERALLY

Zygon, 2023
Theological engagement with quantum physics has, to this day, been dominated by the Copenhagen interpretation. However, philosophers and physicists working in the “quantum foundations” field have largely abandoned the Copenhagen view on account of what ...

Comparing Singlet Testing Schemes

Entropy
We compare schemes for testing whether two parties share a two-qubit singlet state. The first, standard, scheme tests Braunstein–Caves (or CHSH) inequalities, comparing the correlations of local measurements drawn from a fixed finite set against the ...

Against the 'No-Go' Philosophy of Quantum Mechanics [PDF]

, 2013
In the area of the foundations of quantum mechanics a true industry appears to have developed in the last decades, with the aim of proving as many results as possible concerning what there cannot be in the quantum realm. In principle, the significance of

A Generic Model for Quantum Measurements

Entropy, 2019
In previous articles, we presented a derivation of Born’s rule and unitary transforms in Quantum Mechanics (QM), from a simple set of axioms built upon a physical phenomenology of quantization—physically, the structure of QM results of an ...
