Abstract

The switching time of a qubit gate consisting of a three-terminal double-barrier SINIS junction is examined. The quantum states |0〉 and |1〉 are associated with conventional and unconventional Josephson currents. The switching time, τ_sw, and decoherence (dephasing) time, τ_φ, of such a device are computed. The mentioned switching characteristics are closely related to the junction geometry and to the recombination time of quasiparticles from the narrow Andreev bound state level into the superfluid condensate.
