Quantum Error Code 90
Quant. Phys. Preprint at http://arXiv.org/abs/1407.5103 (2014).18.Kubica, A. & Beverland, M. This is an important consideration as we search for schemes that realize fault-tolerant quantum computation with a low cost in quantum resources. http://vealcine.com/quantum-error/quantum-error-code.php
The data show that pth converges to psus∼0.31% where we fit for values N≤8. We evaluate the variables in equation (4) as A∼0.033, α∼0.516 and β∼0.822 using ∼5,000 CPU hours with data for N≤10. Importantly, we require that the lattice has four boundaries, distinguished by colors from set .Single-shot error correctionA quantum error-correcting code is designed to identify and correct errors.

We estimate a sustainable error rate of psus∼0.31% using an efficient clustering decoding scheme34,35,36,37,38,39 that runs in time 35, where the distance of the code is d=L+2 (ref. 7). Phys. We see this using the fitting functionsFigure 8: Variation in constant values α and β plotted against the number of error-correction cycles.Unitless values, α and β, plotted as a function of A physical error is a Pauli-X error on a qubit, whereas a measurement error returns the opposite outcome of the correct reading.

By measuring all the faces of the lattice, we redundantly recover each stabilizer eigenvalue three times where the three outcomes of a given cell are constrained to agree. A.
