PhysicsCould we get quantum spookiness even without entanglement? Particles of light travelling through a maze of devices seem to have passed a famous test for entanglement – without being entangled at all News
PhysicsGiant atoms 'trapped' for record time at room temperature Putting unusually large atoms in a box with cold copper sides helped researchers control them for an unprecedented 50 minutes at room-temperature, an improvement necessary for building more powerful quantum computers and simulators News
