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 ...

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

Scientists observe unusual interference phenomena by scattering laser light from two atoms trapped inside an optical resonator. MPQ scientists observe unusual interference phenomena by scattering ...

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

(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 ...

We’ve all seen recreations of the famous double-slit experiment, which showed that light can behave both as a wave and as a particle. Or rather, it’s likely that what we’ve seen is the results of the ...

AN ICONIC physics experiment may be hiding more than we ever realised about the nature of reality. The classic “double-slit” experiment reveals the strange duality of the quantum world, but it may ...
