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 ...

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

The original paper by Kim et al. on the Delayed Choice Quantum Eraser suggests the concept of retrocausality, which stems ...

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 ...
