Quantum physicists are familiar with wonky, seemingly nonsensical phenomena: atoms and molecules sometimes act as particles, sometimes as waves; particles can be connected to one another by a “spooky ...

In a quantum experiment, scientists observed photons spending ‘negative time’ in a cloud of rubidium atoms. This is likely caused by the fact that photons move faster when exciting these atoms than ...
