Abstract
Quantum-state control of an artificial two-level system was demonstrated in a small-Josephson-junction device: a single- Cooper-pair boat With a highs peed, but well-tailored, gate-voltage pulse, we nonadiabatically controlled the time evolution of the quantum state, and observed coherent oscillation s between the two levels. We present a detailed description of the experime ntal conditions for the observation.
