Does it have enough error-corrected qubits to actually do something useful, or is it a high-tech piece of luxury furniture?

Does it have enough error-corrected qubits to actually do something useful, or is it a high-tech piece of luxury furniture?
- jebej 8y agoThe latter. More seriously though, there won't be a true error corrected quantum computer for a long time. People are hoping that there can be useful applications with imperfect physical qubits.
- wahern 8y agoAt the very least the machines are being used to experimentally verify quantum correction algorithms. See, e.g., https://arxiv.org/abs/1708.02297 https://arxiv.org/abs/1708.02297 and https://arxiv.org/abs/1709.01866 https://arxiv.org/abs/1709.01866 and https://arxiv.org/pdf/1709.00990.pdf https://arxiv.org/pdf/1709.00990.pdf
- kilo_bravo_3 8y agoIsn't that a bit like asking the developers of the Colossus "Does it have enough thyratron ring stores to actually do something useful, or is it just a high-tech piece of boolean operation counting machinery?" Geez, chop chop, make with the general purpose computer already, Tommy Flowers (or should I say Tommy "spent billions making a useless counting machine" Fraudlowers).

- frankchn 8y agoMaybe a better question to ask is whether the IBM Q System One can do anything faster/better/cheaper than existing classical computers? After all, the Colossus was able to aid in the cryptanalysis of the Lorenz cipher, where existing techniques would have been impractical.
