Quantum tunnelling — when a particle skips through a barrier that classical physics would forbid — happens faster when objects have less energy, find physicists who worked out a way to probe photons ...

In the everyday world that humans experience, objects behave in a predictable way, explained by classical physics. One of the important aspects of classical physics is that nothing, not even ...

Ask a bunch of physicists to explain a quantum experiment and you’re unlikely to get the same description twice. Everyone agrees that the mathematical framework of quantum mechanics is peerless at ...

The theory of quantum mechanics has transformed daily life since being proposed a century ago, yet how it works remains a mystery—and physicists are deeply divided about what is actually going on, a ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in physics." The first step toward quantum gravity, the "holy grail of physics," may ...

A quantum computer has reached new heights. The first quantum computer in space is now orbiting Earth on a satellite, scientists report. Launched on June 23, the computer had to be designed to fit in ...

"These single atoms are like the smallest slits you could possibly build." For over 100 years, quantum physics has taught us that light is both a wave and a particle. Now, researchers at the ...
