The gravity-mediated entanglement experiments employ concepts from quantum information to argue that if gravitational interaction creates entanglement between two systems, then gravity cannot be described by a classical system.

We revisit the motion of test particles in quantum-gravitational backgrounds by introducing the concept of q–desics, quantum-corrected analogs of classical geodesics.

Quantum networks are emerging as powerful platforms for sensing, communication, and fundamental tests of physics.

Despite the obvious fact that systems weakly coupled to a thermal bath will generically reach thermal equilibrium, up until recently this was proven to hold only for small quantum systems.

51 years ago Hawking predicted that black holes had a temperature and could evaporate.

Local realism is the worldview in which physical properties of objects exist independently of measurement and where physical influences cannot travel faster than the speed of light—aligned with common human intuition.
