Distinguishability-induced many-body decoherence

Dittel, Christoph LU and Buchleitner, Andreas (2024) In New Journal of Physics 26(12).
Abstract

We show that many-body interference phenomena are exponentially suppressed in the particle number, if the identical quantum objects brought to interference acquire a finite level of distinguishability through statistical mixing of some internal, unobserved degrees of freedom. We discuss consequences for cold atom and photonic circuitry experiments.
