Distinguishing Indistinguishabilities: Logic and Ontology from Quantum Particles to Processes

This book offers an investigation of quantum indistinguishability, showing how it raises fundamental questions about the ontology, identity, and individuality of quantum objects and processes. It considers indistinguishability as an essential ontological aspect of quantum systems rather than a purely epistemic one. This perspective influences how one interprets the formalism, frames the metaphysics of quantum objects, and shapes the analysis and development of mathematical representations. The book's approach to indistinguishability is interdisciplinary, combining physics, philosophy, logic, and mathematics to examine different interpretations and formal frameworks. Its scope extends beyond the typical treatment of indistinguishability as mainly related to particles, and it explores multiple forms of indistinguishability, including processes, states, and paths. This volume will appeal to philosophers of physics, philosophers of science, logicians, mathematical physicists, quantum foundations researchers, and advanced students.
