A new era of technology has been set in motion by the insights of the three scientists who won the physics prize. Over the course of several decades, experiments have been carried out by Aspect, Clauser, and Zeilinger.

Their work focuses on a phenomenon called quantum entanglement, in which two or more particles become correlated with each other so that they behave as if they were single units. Changing the properties of one particle in an entangled pair will instantly change the other, no matter how far apart the particles are. They could be near each other. Einstein was not a fan of the nature of quantum mechanics. The rules of special relativity state that nothing could travel faster than the speed of light. Information could travel between entangled particles if they were separated.
