Quantum computers don't appear to require anything more than routine
non-relativistic quantum mechanics. As such making one appears to
be a (very difficult) problem in applied physics, applied mathematics,
materials engineering and nano-fabrication. I've not seen any
evidence that building scalable QC or proving it impossible requires
new insights into theoretical physics.
The Quantum Mechanics of ordinary materials (found outside of stars
and particle accelerators) has not changed in decades.
Does anyone know of any credible references to suggest that QC is
bottle-necked on progress in Physics beyond QED (let alone beyond
the Standard Model)?
