I realize this is a minority opinion, and goes against all theories of how quantum computing works, but I just cannot believe that nature will allow us to reliably compute with amplitudes as small as 2^-256. I still suspect something will break down as we approach and move below the planck scale.

Fun fact: the Planck mass is about 22 micrograms, about the amount of Vitamin D in a typical multivitamin supplement, and the corresponding derived Planck momentum is 6.5 kg m/s, which is around how hard a child kicks a soccer ball. Nothing inherently special or limiting about these.

		If you look at Planck units or any dimensionless set of physical units, you will see that mass stands apart from others units. There’s like a factor 10^15 or something like this, i.e. we can’t scale all physical units to be around the same values, something is going with mass and gravity that makes it different than others
