In
quantum mechanics, the EPR paradox is a
thought experiment which demonstrates that the result of a measurement performed on one part of a quantum system can have an instantaneous effect on the result of a measurement performed on another part, regardless of the distance separating the two parts. This runs counter to the intuition of
special relativity, which states that
information cannot be transmitted faster than the
speed of light. "EPR" stands for
Albert Einstein,
Boris Podolsky, and
Nathan Rosen, who introduced the thought experiment in a
1935 paper to argue that quantum mechanics is not a complete physical theory. It is sometimes referred to as the EPRB paradox for
David Bohm, who converted the original thought experiment into something closer to being experimentally testable.
The EPR paradox is a
paradox in the following sense: if one takes quantum mechanics and adds some seemingly reasonable conditions (referred to as "locality", "realism", and "completeness"), then one obtains a
contradiction. However, quantum mechanics by itself does not appear to be internally inconsistent, nor -- as it turns out -- does it contradict relativity. As a result of further theoretical and experimental developments since the original EPR paper, most physicists today regard the EPR paradox as an illustration of how quantum mechanics violates
classical intuitions, and not as an indication that quantum mechanics is fundamentally flawed.
