Phys. Rev. Lett. 81, 5039–5043 (1998)Violation of Bell's Inequality under Strict Einstein Locality ConditionsReceived 6 August 1998; published in the issue dated 7 December 1998 We observe strong violation of Bell's inequality in an Einstein-Podolsky-Rosen-type experiment with independent observers. Our experiment definitely implements the ideas behind the well-known work by Aspect et al. We for the first time fully enforce the condition of locality, a central assumption in the derivation of Bell's theorem. The necessary spacelike separation of the observations is achieved by sufficient physical distance between the measurement stations, by ultrafast and random setting of the analyzers, and by completely independent data registration. © 1998 The American Physical Society URL:
