Prospects for quantum coherent computation using superconducting electronics

We discuss the prospects and challenges for implementing a quantum computer using superconducting electronics. It appears that Josephson junction devices operating at milli-Kelvin temperatures can achieve a quantum dephasing time of milliseconds, allowing quantum coherent computations of 10/sup 10/ or more steps. This figure of merit is comparable to that of atomic systems currently being studied for quantum computation.
