       | There's an awful lot of handwaving in this blog post. I'm sorry,

       | require exponentially high precision, but there doesn't seem to
       | be a strong argument for why that doesn't apply to quantum
       | computers. We haven't experimentally demonstrated quantum
       | computing at sufficient scales to prove that the required number
       | of physical cubits to perform error correction doesn't scale
       | exponentially.
