Will it work out? Will investors see profit? Who knows. I like Sabine Hossenfelder the youtube physicist. Neil DeGrasse Tyson gets a lot of attention, obviously, but if you actually want to learn something— watch her.
It’s a good thing we didn’t have social media during the Industrial Revolution.
Steam power? It’ll never catch on!
Power looms? Who needs them?
Locomotives and rails? Bah, going 15 mph is dangerous! Ridiculous!
Steamboat? Pshaw! They blow up!
Electricity? You could get electrocuted!
Automobiles? Why? I’ve got trusty old Dobbin in the barn!
Or they might.
It’s the “uncertainty principle” 😊
The world’s leading quantum computing company makes a profit every year.
IBM.
I spent the day with a physicist at my alma mater; he is the head of his department’s quantum computing project. He talked about the practical problems in the field, and they’re daunting. The three biggest ones are stability, signal-to-noise ratio, and interfacing to outside (i.e. non-quantum) electronics. In each of these areas, improvements on the order of four or five orders of magnitude have yet to be made.
That’s not to say they won’t be made. In conventional electronics, specifically in the field of semiconductors and integrated circuits, improvements of six or seven orders of magnitude have been made, but we’ve been working on it for more than seventy years.
Bkmk
I’d like to get me one of them quantum computers. How tiny is the keyboard and how fine are the fonts?
You’re right! One can learn a lot from physicist Sabine Hossenfelder. All one can learn from Neil DeGrasse Tyson is atheism, which is totally false!
Meanwhile, we may or may not be able to develop quantum computers. But humans will never go to Mars!!
Heisenberg Uncertainty Principle. I’m not sure how they would overcome that with quantum processors.
Regarding Sabine, I often just don’t get the German sense of humor.
They already work. I’ve seen a first hand demonstration, and on the specific tasks they are programmed to do, they literally blow the performance of standard computers away. What they are limited by, primarily, is the variety of things that they can do. They are not general purpose machines, but rather machines that can only do very specific computations. But those computations can be done at speeds that defy in some ways our understanding of how they were done that quickly in our current dimensional time/space. That’s the other main limitation, but they will eventually make progress on that too, I would suspect.
Schrodingers cat smells a rat.
Great theories, but worthless until they are applied and engineered to produce meaningful results. Key trigger is the “just around the corner”, “provided positive result in laboratory testing”, etc.
