I definitely think QC will answer a ton of important physics/quantum mechanics questions. Worst case, if research into QC ends up proving that no feasible error correction strategy can overcome the inherent noise, that would be a major advancement. At present, QC is more promising than that. Scientifically it’s comparable to XENON, LIGO or the LHC. The worry is that from a market perspective QC might turn out like nuclear fusion.
