Underground experiment rules out gravity model for quantum decoherence
Researchers at Italy's INFN Gran Sasso National Laboratory published results in June 2026 that exclude a gravity-based theory for quantum decoherence.
New findings narrow explanations
Scientists conducted an underground experiment to test how quantum behavior disappears in larger objects. The study specifically tested a prominent theory linking gravity to this fading process. Results published in the New Journal of Physics show that gravity does not cause decoherence.
VIP Collaboration leads research
Catalina Curceanu serves as director of research for the VIP Collaboration at INFN-LNF. She stated that understanding why quantum rules fail in the macroscopic world remains a deep question. The collaboration operates out of the National Laboratory of Frascati in Italy.
Study location and timing
The experiment took place at the INFN Gran Sasso National Laboratory. This facility is located in Italy and provided the necessary conditions for the test. The paper detailing these results appeared online in June 2026.
