Firstly I would say I agree with you that there most certainly are major companies that enhance their results. I would be curious to read the paper or proof of the IBM quantum computer issues.
However the readout is always done by a classical computer at the moment. We aren't at the stage where we have an integrated system that can use photonic chip say from start to finish. That's not a sign it's fraudulent, that's just the stage we are at.
Secondly, there are fraudulent claims in every area of research or enhanced claims, that doesn't mean none of the science is valid.
What's your background here?
"What's your background here?" you want to play status games to advance your fraudulent "industry"?
the audacity.
The stage we are at and that we will never leave is that quantum "computers" are just sources of very expensive random noise.
there is no credible path towards leaving this stage.
The only response to that is an appeal to "authority". It is becoming more and more apparent that only low quality "show man" type people are left in this clown "industry". Trumps endorsement with the white house push for "quantum" might be the last nail in the coffin.
There is no money coming into this field without practically useful results and there wont be any.
A few billion through penny stock scams a few billion through government grant graft. What a sad little show. Only stupid people and conman types will join this "field"
