EPR refers to a paper that three physicists––Albert Einstein, Boris Podolsky, and Nathan Rosen––wrote in 1935 while at IAS, “Can Quantum-Mechanical Description of Physical Reality be Considered Complete?” The idea of the paper arose during an IAS teatime conversation between Einstein, Podolsky, and Rosen and introduced an ongoing debate over quantum mechanics. The publication of the EPR paper was heralded in the New York Times under the headline "Einstein Attacks Quantum Theory," reporting Einstein's view that quantum mechanics is "correct" but not "complete."
