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 ...

When two or more light waves interact with one another, they result in the formation of different interference patterns. British physicist Thomas Young first demonstrated and explained these patterns ...

MIT physicists have performed an idealized version of one of the most famous experiments in quantum physics. Their findings demonstrate, with atomic-level precision, the dual yet evasive nature of ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

The famous double slit experiment shows that particles can travel on two paths at the same time -- but only by looking at a lot of particles and analysing the results statistically. Now a ...
