Fundamental law of physics demonstrated using quantum objects

The principle of least action has been a key law of physics since the 18th century, but has only now been directly observed in the quantum realm thanks to an experiment with single particles of light

Quantum entanglement. Conceptual artwork of a pair of entangled quantum particles or events (left and right) interacting at a distance. Quantum entanglement is one of the consequences of quantum theory. Two particles will appear to be linked across space and time, with changes to one of the particles (such as an observation or measurement) affecting the other one. This instantaneous effect appears to be independent of both space and time, meaning that, in the quantum realm, effect may precede cause.
