Fault-tolerant quantum computation versus Gaussian noise

Quantum Physics 2009-03-17 v1 Mesoscale and Nanoscale Physics Superconductivity

Abstract

We study the robustness of a fault-tolerant quantum computer subject to Gaussian non-Markovian quantum noise, and we show that scalable quantum computation is possible if the noise power spectrum satisfies an appropriate "threshold condition." Our condition is less sensitive to very-high-frequency noise than previously derived threshold conditions for non-Markovian noise.
