Precision experiment puts pressure on quantum collapse theories - EurekAlert!

A precision experiment is squeezing the life out of rival theories that try to explain why quantum superpositions "collapse" into definite reality — and the results could rewrite our understanding of measurement itself.

Theory Briefing
- Quantum particles can exist in superposition until measured — but no one agrees on why or how that collapse actually happens.
- The new precision experiment sets tighter limits on spontaneous collapse models, shrinking the theoretical space where rivals to standard quantum mechanics can hide.
- At stake is the quantum measurement problem — a foundational puzzle about whether collapse is a physical process or just an update in an observer's knowledge.
