Who Proposed Quantum Entanglement?

The phenomenon of entanglement was first proposed by Albert Einstein and colleagues in the 1930s. At that time, many questioned the validity of entanglement, including Einstein himself. Over the years and in various experiments, however, researchers have generated entangled particles that have supported the theory.

Did Einstein predict quantum entanglement?

Albert Einstein famously said that quantum mechanics should allow two objects to affect each other's behaviour instantly across vast distances, something he dubbed “spooky action at a distance”¹. Decades after his death, experiments confirmed this.

Where did the idea of quantum entanglement come from?

Following the EPR paper, Erwin Schrödinger wrote a letter to Einstein in German in which he used the word Verschränkung (translated by himself as entanglement) "to describe the correlations between two particles that interact and then separate, as in the EPR experiment."
