An optical method for quantum computing that makes use of nonlocal effects to construct the quantum gates themselves. A nonlocal interaction in which pairs of atoms interchange two photons produces a large nonlinear phase shift. These nonlinear phase shifts are used to construct quantum logic gates, such as a Controlled-NOT.

L'invention concerne un procédé optique qui permet le calcul quantique et qui utilise les effets non locaux pour construire les portes quantiques elles-mêmes. Une interaction non locale, dans laquelle les paires d'atomes échangent deux photons, produit un déphasage non linéaire important. Ces déphasages non linéaires sont utilisés pour construire des portes logiques quantiques, telles qu'un NON commandé.
