Threshold Estimates for Homogeneous Ancillae
Bryan Eastin · arXiv (Cornell University) · 2006
I describe a procedure for estimating thresholds for quantum computation as a function of error model given the availability of ancillae prepared in logical states with independent, identically distributed errors. The thresholds are determined via a simple counting argument performed on a single qubit of an infinitely large CSS code. I give concrete examples of thresholds thus achievable for both Steane and Knill style fault tolerant implementations.
