Tabletop quantum experiment could detect gravitational waves

Predicted by Einstein's general theory of relativity, gravitational waves are ripples in space-time generated by certain movements of massive objects. They are important to study because they allow us to detect events in ...

Quantum fluctuations can jiggle objects on the human scale

The universe, as seen through the lens of quantum mechanics, is a noisy, crackling space where particles blink constantly in and out of existence, creating a background of quantum noise whose effects are normally far too ...

Quantum fridge works by superposing the order of events

Ever tried defrosting your dinner by popping it in one identical freezer after another? Strange as it sounds, recent studies of indefinite causal order—in which different orders of events are quantum superposed—suggest ...
