The subtlest experiment in quantum mechanics is also one of the simplest: send a stream of particles through two openings in a barrier, and you’ll produce an interference pattern because the particles ...

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 ...

Can a photon be caught behaving like a wave and a particle in the same run of an experiment? For almost a century, that ...

About time: Romain Tirole from Imperial College London and colleagues have created a temporal version of the famous double-slit experiment (Courtesy: Thomas Angus, Imperial College London) Thomas ...

One of the best-known examples of the counterintuitive behavior seen in the quantum world is the double-slit experiment. Take a piece of material that blocks light and cut two small slits in it; hit ...
