Optical approach to quantum computing

We describe an on-going experimental investigation of a newly predicted mechanism for the production of nonlinear interactions between two photons. This mechanism involves nonlocal cooperative effects between pairs of atoms and exists only at the quantum level. An optical approach to quantum computing based on this effect may have many practical advantages.
