A new computing architecture composed of Coulomb‐coupled optically pumped two‐state nanodevices is proposed. A new four‐level device, built from two coupled two‐state devices called ‘molecular pair’, is introduced. Simulations on the equivalent circuit models of two‐dimensional arrays composed of molecular pairs suggest that non‐reciprocal pipelining wires, ring oscillators and NAND gates can be built. It is shown that the optically pumped molecular pairs do not stack in meta‐stable states, and they restore logic levels. Copyright © 2001 John Wiley & Sons, Ltd.
