A new study proposes that quantum information, encoded in entanglement entropy, directly shapes the fabric of spacetime, offering a fresh path toward unifying gravity and quantum mechanics.

Published in Annals of Physics, the paper presents a reformulation of Einstein’s field equations, arguing that gravity is not just a response to mass and energy, but also to the information structure of quantum fields. This shift, if validated, would mark a fundamental transformation in how physicists understand both gravity and quantum computing.

The study, published by Florian Neukart, of the Leiden Institute of Advanced Computer Science, Leiden University and Chief Product Officer of Terra Quantum, introduces the concept of an “informational stress-energy tensor” derived from quantum entanglement entropy.
