Scientists test Einstein’s quantum challenge with one atom, directly measuring when photon paths erase interference stripes.

An experiment measuring a single atom's recoil confirmed that observing a particle destroys interference, settling the ...

Researchers have demonstrated that a nanoparticle of 7,000 sodium atoms can act as a wave, creating a record-setting ...

Thomas Young, born 250 years ago this week, was a polymath who made seminal contributions in fields from physics to Egyptology. But perhaps his most enduring legacy is proving Isaac Newton wrong about ...

Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is still the star of that show. A new, ultra-clean version of this classic test ...

Physicists have now managed to track the passage of time inside a quantum event without using anything that looks like a traditional clock. Instead of ticking gears or oscillating crystals, they read ...

Scientists recreated one of the most important experiments in the history of physics—but this time, they used antimatter instead of regular matter. All matter particles have a corresponding antimatter ...

(Inside Science) — One of the strangest things about quantum mechanics is that a particle can act like a wave. In particular, in a double-slit experiment, individual particles that are shot through a ...

Even younger: illustration of the new double-slit experiment using resonant inelastic X-ray scattering on an iridium oxide crystal. An intense beam of high-energy X-ray photons (violet) hits two ...
