Compatible Quantum Theory [PDF]
Reports on Progress in Physics, 2014 Formulations of quantum mechanics can be characterized as realistic, operationalist, or a combination of the two. In this paper a realistic theory is defined as describing a closed system entirely by means of entities and concepts pertaining to the ...

Reviews of Modern Physics, 1998 I discuss the general principles underlying quantum field theory, and attempt to identify its most profound consequences. The deepest of these consequences result from the infinite number of degrees of freedom invoked to implement locality.

Quantum Microeconomics Theory [PDF]
SSRN Electronic Journal, 2015 The quantum macroeconomics theory is formulated for the first time, assuming that the business cycle has the discrete-time oscillations spectrum in analogy with the electronics excitations discrete-time spectrum in the Bohr’s atom model in the quantum physics.

Quantum Embedding Theories [PDF]
Accounts of Chemical Research, 2016 In complex systems, it is often the case that the region of interest forms only one part of a much larger system. The idea of joining two different quantum simulations - a high level calculation on the active region of interest, and a low level calculation on its environment - formally defines a quantum embedding.

Weak versus Deterministic Macroscopic Realism, and Einstein–Podolsky–Rosen’s Elements of Reality
Entropy, 2023 The violation of a Leggett–Garg inequality confirms the incompatibility between quantum mechanics and the combined premises (called macro-realism) of macroscopic realism (MR) and noninvasive measurability (NIM).

Simulating Gaussian boson sampling quantum computers
AAPPS Bulletin, 2023 A growing cohort of experimental linear photonic networks implementing Gaussian boson sampling (GBS) have now claimed quantum advantage. However, many open questions remain on how to effectively verify these experimental results, as scalable methods are ...

Simplified quantum optical Stokes observables and Bell’s theorem
Scientific Reports, 2022 We discuss a simplified form of Stokes operators for quantum optical fields that involve the known concept of binning. Behind polarization analyzer photon numbers (more generally intensities) are measured.

Foundations of Physics, 2012 We present a discrete model theory similar in structure to ordinary quantum mechanics, but based on a finite field instead of complex amplitudes. The interpretation of this theory involves only the "modal" concepts of possibility and necessity rather than quantitative probability measures.

A Macroscopic Quantum Three-Box Paradox: Finding Consistency with Weak Macroscopic Realism
Entropy, 2023 The quantum three-box paradox considers a ball prepared in a superposition of being in any one of three boxes. Bob makes measurements by opening either box 1 or box 2.

Fortschritte der Physik, 2016 We present quantum holonomy theory, which is a non‐perturbative theory of quantum gravity coupled to fermionic degrees of freedom. The theory is based on a ‐algebra that involves holonomy‐diffeo‐morphisms on a 3‐dimensional manifold and which encodes the canonical commutation relations of canonical quantum gravity formulated in terms of Ashtekar ...
