Abstract
A method and apparatus for transmitting information using the phenomenon of quantum entanglement. Two streams of quantum-entangled particles are emitted from a source. Performing a measurement on one of the streams results in the observable destruction of interference on the other stream. Information is transmitted by modulating the performance of the measurement on the first stream, and received by observing the presence or absence of interference in the second stream.
