Overview

• Just over a third of respondents (36%) endorsed the Copenhagen interpretation as their preferred framework for quantum theory.
• Only 15% of those surveyed backed the Many-Worlds interpretation, leaving most researchers unconvinced by its branching-universe premise.
• Opinions diverge sharply on the wavefunction’s ontology: 36% treat it as a physical entity, 47% as a computational tool and 8% as reflecting subjective knowledge.
• Data from the XENONnT experiment have ruled out several spontaneous collapse models by imposing new constraints on Schrödinger’s equation.
• Ongoing foundational research continues to drive advances in quantum computing and cryptography while fueling debate over a more comprehensive successor theory.
