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 ...

A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

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

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 ...

Athought experiment at the heart of an argument between famed physicists Albert Einstein and Niels Bohr in 1927 has finally ...

A sensitive matter-wave interferometer measuring moiré fringes offers force sensitivity comparable to quantum interference ...

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 ...

The double-slit connection In their paper, the authors draw an elegant analogy to the famous double-slit experiment, where particles like electrons produce interference patterns when passed through ...
