I bet you quantum computing will go the way of Newtonian physics - wrong and only proven so by our ability to measure things.
It's as if Newton insisted that he was right despite the orbit of mercury being weird, and blaming his telescope.
Physics is just a description of reality. If your business depends on reality being the same as the model, then you're going to have an expensive time.
We still use Newton's equations for building rockets (and a lot of other things). A theory being replaced by a better one does not mean devices motivated by the obsoleted theory stop working...
We use general relativity for anything fast moving I think. Not sure, but pretty sure. GPS wouldn't work with newton. But that's the point, newton mostly works to within an error of measurement
Examples of using GR are few, GPS being the most prominent one, another being astronomy. Making this point, SR would be a better example.
Maybe a better description would be "we use GR to describe extremely precise time measurements, or the movement of extremely large things". The latter has not yet lead to any devices being built, as far as I know.
"It turns out that GPS must account for both special relativity and general relativity to deliver position at 1-meter level and time at 100-nanosecond level to its users."
Uuh no? Quantum computing relies on some aspects of quantum physics, that at this point, have been thoroughly and extensively experimentally verified.
If there are objections to quantum computing, and I believe there are many, those are to be found in questioning the capability of current engineering to build a quantum computer, or the usefulness of one if it could be built.
As the old saying goes: the proof is in the pudding. And quantum computing has produced zero pudding. All hype, and zero pudding. When they actually do something useful (like the equivalent of general relativity and solving GPS), then we can see it as a useful theory.
"In early May, news reports gushed that a quantum computation device had for the first time outperformed classical computers, solving certain problems thousands of times faster. The media coverage sent ripples of excitement through the technology community. A full-on quantum computer, if ever built, would revolutionize large swathes of computer science, running many algorithms dramatically faster, including one that could crack most encryption protocols in use today.
"Over the following weeks, however, a vigorous controversy surfaced among quantum computation researchers. Experts argued over whether the device, created by D-Wave Systems, in Burnaby, British Columbia, really offers the claimed speedups, whether it works the way the company thinks it does, and even whether it is really harnessing the counterintuitive weirdness of quantum physics, which governs the world of elementary particles such as electrons and photons."
And 12 years from now we will be reading the same things. It's just shocking the amount of faith people have in this physics. Physics, to me, is a dying subject. The future is engineering and computing.
Also, how about thinking about it this way: either there's this magical property of the universe that promises to do these magical things which no one can even dream of achieving otherwise, or there's something wrong with physicists' interpretation of physics. Oh, and they haven't proved it yet but promise they will, very soon.
