How Do Scientists Explain Quantum Entanglement?

In this video, four Caltech faculty members explain quantum entanglement, each sharing metaphors and concepts that help describe this mind-bending phenomenon.

Entanglement is at the heart of quantum physics and future quantum technologies. Like other quantum phenomena, entanglement reveals itself at tiny, subatomic scales. When two particles, such as a pair of photons or electrons, become entangled, they can remain connected even when separated by vast distances. In the same way that a ballet or tango emerges from individual dancers, entanglement arises from the connection between particles. It is what scientists call an emergent property.
