# Noise thresholds for optical quantum computers.

@article{Dawson2006NoiseTF, title={Noise thresholds for optical quantum computers.}, author={Christopher M. Dawson and Henry L. Haselgrove and Michael A. Nielsen}, journal={Physical review letters}, year={2006}, volume={96 2}, pages={ 020501 } }

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).

This work shows that topological FTQC schemes, which are known to have high error thresholds, are also extremely robust against losses, and demonstrates that these schemes tolerate loss rates up to 24.9%, determined by bond percolation on a cubic lattice.

One-way quantum computing in the optical frequency comb.

This work proposes a scalable method that uses a single, multimode optical parametric oscillator (OPO) and generates a continuous-variable cluster state, universal for quantum computation, with quantum information encoded in the quadratures of the optical frequency comb of the OPO.

Loss tolerant linear optical quantum memory by measurement-based quantum computing
