Bell's Theorem

Proves no local hidden variable theory can reproduce all predictions of quantum mechanics.

Core Principles & Analysis

• Formulated by John Stewart Bell in 1964 in response to the Einstein-Podolsky-Rosen paradox.
• Derives inequalities that any local hidden variable theory must satisfy but quantum mechanics violates.
• Experimental tests of its inequalities earned Clauser, Aspect, and Zeilinger the 2022 Nobel Prize in Physics.
