Quantum computing ONLY allows for unitary operations. At least in theory, as far as I know.
Could we use Quantum Computing to test the limits of Quantum Mechanics or explore the emergence of quantum physics from another bigger scheme?

@riemannium wasnt talking about riemannium. was talking about your blog cited. do you have a university degree? anyway the idea of reformulating QM as you mention is being pursued by some narrow band of experts... the idea of "testing" QM (vs classical physics) via QComputing while would be regarded as quite radical, laughable, useless or meaningless by many has occured to me, think there is some possibility of it on the horizon...
Yes, I have even a master degree, and a second one in course (but slowed due to my health issues) ...The first is on Theoretical Physics, the second is on Astronomy and Astrophysicis but I have not finished it yet...
Well, the idea is not yet reformating the QM...But understanding how QM emerge itself...Gauge theory and gravity could be emergent from another big scheme yet to come.
Of course, I assume no one will support this, and we have today two radical branches...Those, the majority, who think quantum is the final end...And gravity should be quantized...
Likely it is the preferred option...The minority band tries to think QM as effective...Even thooft or weinberg now support it, with differences of course.
But my question is much more general...I am sure quantum computing can test quantum limits itself...I remember a paper about this but I don't manage to find it again, lol...I am a bit chaotic with references...Lol
@riemannium there is some chg/ new thinking in the air, have blogged on it over the yrs. am looking esp into fluid/ hydrodynamics as a unifying principle as seen in the breakthru experiments of Couder et al and articulated in detail by Bush, urge you to look into it all. lately am finding hydrodynamics aspects to GR and am gonna blog on that coming up. also Verlinde ideas on emergent gravity are gaining some significant traction etc. vzn1.wordpress.com/category/physics
@riemannium a big fan myself, cite him highly, but would not really say t' hooft "accepts" QM... regard him as a leading iconoclast/ visionary of which unf very few are following, quite to the contrary, showing the inherent extreme obstacles to this direction/ line of work/ inquiry/ research...
@vzn Fan of Verlide's theory? It is just a remake of emergence...Gauge theory and gravity are likely emergent from another theory...Even string theory is not really fundamental...
't hooft thinks quantum mechanics is effective. He is a Nobel Prize and smart, so I think it has the right to think that way...Even Lee Smolin wrote a paper of QM as effective theory that disliked stringers...Anyway, without experimental hints we are reaching limits. The Higgs-like particle is a mystery and dark matter does not appear in the TeV scale, it seems that likely the PeV scale is the real thing...
How much time to get a PeVatron? The Chinese collider will have only 0.1 PeV...Neutrino data from IceCube seems to point out that something happens at PeV, no neutrino above several PeV has been found, it would be very interesting to elucidate a reason for that...
yes, after stellar run by LHC, and uncountable billions $ later, it looks like there is some pressure on the theory now to catch up, to go forward, to get ahead. dark matter may be some of the latest areas of revisions/ insight.
@vzn Although, if I needed to place a bet, it would be that some classical system can replicate any QM one. Maybe that is obvious. I'm not informed enough to judge whether computational efficiency is a deciding factor.
@EmilioPisanty I suppose the main reason to care would be curiosity. If there is only a tiny speck of uncertainty regarding QM, why not completely focus on that speck? That is: if you care about the 'underlying truth'. Then again, I tend to think that they are potentially equivalent; as in: nature isn't quantum or (adapted) classical, it can be described by both (and I don't know if it even matters what nature's hardware is).
