Abstract
A new superconducting logic device operating as a three-phase shift register has been proposed. The new device is constructed with a long chain of coupled superconducting quantum interferometers, where shift register operations are performed through successive transfer of single flux quanta along the chain. Computer simulations demonstrate that the transfer frequency higher than 20 GHz and the energy dissipation lower than 10-17 J per bit can be expected. The new device is one order higher in speed and two orders lower in energy dissipation than a conventional superconducting current-steering circuit.
