Quantum entanglement, conceptual illustration - stock illustration

Quantum entanglement. Conceptual illustration of a pair of entangled quantum particles or events 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
