My understanding is exactly the opposite ... quantum computing is a giant flapdoodle. If I’m wrong, I’m wrong.
You are correct. Total bunk. My BIL is an ultra-lefty physicist that works on this crap and says that the idiots that don't believe in QC are on the level of climate change deniers.
I did a LOT of research on QC (as an engineer it was fascinating at first), but found out it really WAS like global warming - a scam by college/government teat suckers to get more and more money for decades on end, always saying that their results would be shown in just another 10 years.
Let me explain why QC is impossible on the face of it - simply observing quantum particles will change their "value", therefore any answer to anything you feed this "computer" will be invalidated as soon as it is observed. It's just physics, and there is no way around it. So, don't worry. Our encryption methods are still good as long as we stay ahead of the normal computing tech curve.
I wish you were right but you are not. It’s very real and will begin to emerge in the public in 8 years. Then 5 years from that point it will be everywhere. Kind of like Smart Phones but a lot faster. This is because the machines, automation, drones and the robots will be doing all the work.
The only reason for the mixed message is simply to avoid debate.
