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

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 ...

One of the most famous experiments in quantum physics, which first showed how particles can bizarrely behave like waves, has now been carried out on the largest molecules ever. Researchers have sent ...

Classical Physics (Physics established mostly by Newton), has one property that we may think that is universal, which is, certainty. For example, by using the mathematics of Newton, we can precisely ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Quantum mechanics is one of the most ...

More than 200 years ago, the English scientist Thomas Young carried out a famous test known as the “double-slit experiment”. He shone a beam of light at a screen with two slits in it, and observed the ...

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 international group of physicists has found a way of measuring both the position and the momentum of photons passing through the double-slit experiment, upending the idea that it is impossible to ...

This week, an exciting new experiment has been published in Science. Funnily enough, it repeats an experiment that is over 200 years old, and I am not certain that it teaches us anything new about the ...
