Quantum entanglement defies our understanding of reality. Albert Einstein did not believe it existed and called it “spooky action at a distance” as it appears to defy the laws of physics. But science has proven quantum entanglement to be real.
Within the lab, scientists routinely generate pairs of entangled particles that share a quantum state so fully, that they can be thought of as one quantum object. Entangled particles remain connected even when they are separated by hundreds of miles. There is no known way to differentiate between them as if they are a single entity. The two acting as one continue despite being spatially separated without a physical connection.
