uantum C~~~~ent Computation Using Superconducting Electronics
Mark F. Bocko, Andrea Marie Herr, M. J. Feldman · 1997
We discuss the prospects and challenges for implementing a quantum computer using supercon- ducting 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 lo1* or more steps. This figure of merit is comparable to that of atomic systems currently being studied for quantum computation.
