Method and system for binary signaling via quantum non-locality

Abstract

A method of, and system for, binary signalling via quantum non-locality. The method and system are particularly suitable for rapid communication including superluminal signalling. The method and system use an ensemble of quantum-systems in which the quantum-systems are in pairs, with one quantum-system of each pair being in quantum entanglement with the other quantum-system of each pair. The quantum-systems may comprise particles or parts of particles. The paired quantum-systems are separated into two subgroups, with the quantum-systems of each pair being in different subgroups. The quantum-systems in one subgroup are subjected to an influence, such as a slit, to enhance scattering of the quantum-systems to an extent corresponding to the selected binary signal to be transmitted. The extent of correlated scattering in the quantum-systems in the other subgroup is then detected, the extent of scattering providing an indication of the particular binary signal transmitted. Detection of the extent of correlated scattering involves subjecting the quantum-systems in the other subgroup to a detector slit.
