Protective Measurement and Quantum Reality: Towards a New Understanding of Quantum Mechanics

Published by on

Protective measurements offer an intriguing method for measuring the wave function of a single quantum system. With contributions from leading physicists and philosophers of physics – including two of the original discoverers of this important method – this book explores the concept of protective measurement, investigating its broad applications and deep implications. Addressing both physical and philosophical aspects, it covers… Read more →

Derivation of quantum probabilities from deterministic evolution

Published by on | 2 Responses

T. G. Philbin Physics and Astronomy Department, University of Exeter, Stocker Road, Exeter EX4 4QL, United Kingdom The predictions of quantum mechanics are probabilistic. Quantum probabilities are extracted using a postulate of the theory called the Born rule, the status of which is central to the “measurement problem” of quantum mechanics. Efforts to justify the Born rule from other physical principles, and… Read more →
