- The first ever study of decoherence in superconducting quantum devices (see Ithier, Meeson et al Phys. Rev. B 72, 134519, (2004) identified the fundamental challenge in the development of superconducting quantum computing, the achievement of long-coherence times by the identification and elimination of sources of decoherence. The current paper provided evidence against the applicability of the prevailing decoherence theory, the “standard tunnelling model” and helped establish surface contamination as the source of the decoherence. This in turn has contributed to the present day achievement of ≈ 100 fold increase in superconducting quantum coherence times in measured devices.
