​That's interesting but they can't scale it up to make a full scale machine
just yet because existing error correcting schemes can only do so much and
their error rate ​is still about 6 dB too high. The authors of the paper
admit this but say:

​"​
*However, the requirement for fault tolerance is likely to be satisfied in
the near future by further​ ​improvement of technology or error-correction
protocols*
​"

I hope they're right but getting those last few dB's is hard.
