Experiment and the foundations of quantum physics

Reviews of Modern Physics, 1999
Quantum physics, a child of the early 20th century, is probably the most successful description of nature ever invented by man. The range of phenomena it has been applied to is enormous. It covers phenomena from the elementary-particle level all me way to the physics of the early universe.

Foundations for Quantum Mechanics

Journal of Mathematical Physics, 1970
A discussion is given of the structure of a physical theory and an ``ideal form'' for such a theory is proposed. The essential feature is that all concepts should be defined in operational terms. Quantum (and classical) mechanics is then formulated in this way (the formulation being, however, restricted to the kinematical theory).

Foundations for Quantum Statistics

Journal of Mathematical Physics, 1968
A derivation of Fermi and Bose statistics is given, based on the general structure of quantum mechanics, together with a simple axiom of direct physical significance. The axiom concerns an operation, denoted by ∘, forming the union of two states; ψ ∘φ denotes the state of a compound system whose parts are in the states ψ and φ.

Quantum metaphysics and the foundations of spacetime

2022
The main research programs in quantum gravity tend to suggest in one way or another that most (if not all) spacetime structures are not fundamental. At the same time, work in quantum foundations highlights fundamental features that are in tension with any straightforward spacetime understanding.

Foundations of Quantum Technology

Journal of Computational and Theoretical Nanoscience, 2005
Recent progress in fabrication and control of single quantum systems presage a nascent technology based on quantum principles. We review these principles in the context of specific examples including: quantum dots, quantum electromechanical systems, quantum communication and quantum computation.

Foundations of a quantum probability theory

Journal of Mathematical Physics, 1975
Statistical physical theories are frequently formulated in terms of probabilistic structures founded on a ’’logic of experimentally verifiable propositions.’’ It is argued that to each experimentally verifiable proposition there corresponds an experimental procedure which, in general, alters the state of the system, and is completely characterized by a

Mathematical Foundation for Quantum System

2016
This book introduces group representation theory in terms of quantum theory. For this purpose, this chapter introduces basic concepts of quantum theory, measurement, state, composite system, many-body system, and entanglement. It also prepares mathematical notations for quantum systems.
