Identity and Indiscernibility in Quantum Mechanics cover

This book analyzes metaphysical consequences of the quantum theory of many particles with respect to the fundamental notions of identity, individuality and discernibility. The main focus is on the proper interpretation of the quantum formalism in relation to the role of permutation invariance and the adequate representation of the properties of individual subsystems. Two main approaches to the issue of the individuation of quantum particles are distinguished and thoroughly discussed.  These approaches differ radically with respect to their metaphysical consequences – while one of them implies the complete indiscernibility of quantum particles of the same kind, the other one restores the possibility of discerning individual particles by their properties. We connect the problem of quantum individuation and discernibility with an analysis of the concept of quantum entanglement, and we also discuss identity over time and in counterfactual scenarios.

“This book makes an important contribution to the philosophy of physics, as it is not only an exceptionally clear overview of the work done in the last 50 years on individuality in quantum physics, but also a preliminary work that lays the foundations for a promising new metaphysics of fundamental objects.” (Système d'information en philosophie des sciences, SIPS, February 15, 2023)
“Both for physicists interested in the basics of quantum mechanics and philosophers of science, reading the book can be quite a challenge. However, the efforts of going through it will be highly rewarded. The book is the best and most comprehensive work on the physics and philosophy of quantum particle systems of the same type in world literature.” (Marek Kuś, ZFN Philosophical Problems in Science, November 8, 2022)
