Cold atom experiments are among the most powerful and precise ways of investigating and measuring the universe and exploring ...

Not every day does “time” get into misbehavior, but in a new experiment, photons passing through a fog of ultracold rubidium-85 atoms were shown to spend a negative duration in an excited atomic state ...

The measurement problem in quantum mechanics looks at how an experimental outcome changes, simply by observing it.

Amid high expectations for quantum technology, a new paper in Science reports a proven quantum advantage. In an experiment, ...

He added that the team learned the behaviour of their system in 15 minutes. A comparable classical method would take around 20 million years. The experiment took place in the basement labs at DTU ...

Determining the passage of time in our world of ticking clocks and oscillating pendulums is a simple case of counting the seconds between 'then' and 'now'. Down at the quantum scale of buzzing ...

Researchers find that a photon can spend a negative amount of time in an excited atomic state while passing through a cloud ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

Spacetime ripples from a black hole collision across the cosmos have confirmed weird aspects of black hole physics ...

The advent of web-based platforms for behavioural experimentation has revolutionised the way researchers approach data collection, enabling large-scale, cost-effective studies with diverse populations ...
