Noise Thresholds for Optical Quantum Computers
Open accessAbstract
In this Letter we numerically investigate the fault-tolerant threshold for optical cluster-state quantum computing. We allow both photon loss noise and depolarizing noise (as a general proxy for all local noise), and obtain a threshold region of allowed pairs of values for the two types of noise. Roughly speaking, our results show that scalable optical quantum computing is possible for photon loss probabilities <3 x 10(-3), and for depolarization probabilities <10(-4).

The one-way quantum computer may be advantageously combined with the KLM scheme of optical quantum computation, and fault-tolerant schemes using photons have been developed.
“First, after it was realized 37,42,68 that the one-way quantum computer may be advantageously combined with the KLM scheme of optical quantum computation 7 and fault-tolerant schemes using photons were developed 69-71 .”

In Ref. 69, both photon loss and gate inaccuracies were taken into account, yielding a trade-off curve between the two respective thresholds.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
