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.
