A setup with magnetic microchips suspends a tiny diamond grain with a special defect that glows like a beacon. The particle enters a state of superposition, existing in two places at once. The goal: entangle two such grains via gravity—if successful, it would prove that attraction itself obeys quant

Scientists simulated how gravity alone entangles two massive particles. They devised a setup with two path splitters, where each particle's fate depends on the quantum state of its neighbor. It turned out that the strength of the connection does not depend on mass—whether it's a tiny speck of dust o

Scientists have found that a body smeared across two points simultaneously can repel gravitationally. The weak negative value effect makes attraction turn into a push. This suggests the fabric of spacetime itself follows quantum laws.

The exchange of gravitons between a photon and a rotating mirror gives rise to quantum entanglement. The strength of the link depends on the direction of rotation. This brings us closer to experimentally testing quantum gravity.
