EPR telephone

English

Etymology

From EPR +‎ telephone. From being a method of transmission (telephone) in non-linear quantum physics where faster-than-light (FTL) communication (non-local communication) is possible, as described in the EPR paradox proposed by Einstein, Poldolsky, Rosen, violating relativity. Coined by American physicist Joseph Polchinski in 1990.

Noun

EPR telephone (plural EPR telephones)

1. A method of transmission of information non-locally, allowing FTL communication and back-in-time communication, through application of Steven Weinberg's proposed non-linear fields in quantum physics on entangled particles, accessing hidden variables of the Schrödinger equation.
2. An implementation of this method.
