Locality
Locality is a feature of the world that is suggested by the experience that local causes produce local effects. In quantum mechanics, however, the EPR Paradox conceived of widely separated situations entangled by virtue of their quantum histories, and it is possible for a quantum measurement to have a nonlocal effect. It has sometimes been suggested that nonlocality might form a basis for telepathy or some form of faster-than-light signaling or travel. However, it can be shown that within quantum mechanics it is not possible to transfer information faster than the speed of light by exploiting quantum nonlocality. No two quantum mechanical measurements can be connected to ...
