Abstract

A new variant of the controlled-NOT quantum logic gate is proposed. The gate is based on adiabatic level-crossing dynamics of the q-bits. An important advantage of the adiabatic dynamics, as opposed to the ac-driven Rabi transitions, is its considerable insensitivity to the unavoidable spread of the gate parameters. The gate has a natural implementation in terms of the Cooper pair transport in arrays of small Josephson tunnel junctions. The decoherence rate for this implementation is estimated.
