Phys. Rev. Lett. 92, 117905 (2004) [4 pages]Dynamical Suppression of 1/f Noise Processes in Qubit SystemsReceived 18 September 2003; published 18 March 2004 We investigate the capability of dynamical decoupling techniques to reduce decoherence from a realistic environment generating 1/f noise. The predominance of low frequency modes in the noise profile allows for decoherence scenarios where relatively slow control rates suffice for a drastic improvement. However, the actual figure of merit is very sensitive to the details of the dynamics, with decoupling performance which may deteriorate for non-Gaussian noise and/or high frequency working points. Our results are promising for robust solid-state qubits and beyond. © 2004 The American Physical Society URL:
