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.

Caption Illustration of the double-slit experiment, showing a plane wave (top left) passing through a screen with two gaps. The gaps act as new wave sources and the wavefronts bend to create two sets of circular waves radiating outwards. These two new waves create an interference pattern as they interact. At the point where a wave peak from one hits a wave peak from another, or a trough hits a trough, they reinforce each other; their magnitudes are summed. This is known as constructive interference. Where a trough hits a peak, they cancel each other out. This is known as destructive interference.
