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.
It was always a scam to fleece investors. Hopefully we psyop’d China into diverting large resources into it.
“The three biggest ones are stability, signal-to-noise ratio...”

I take it that the quantum error handling problem is included under this? I believe its a fundamental challenge with quantum computing, at this point.
Hey, Can’t AI fix those problems?
Another major problem is the absence of “software” for the quantum computer. It is harder than most people think to apply the quantum computer to solve meaningful problems. There are some well-known applications, like factoring integers, but the number of known useful applications is still limited.
We’ll said. But many breakthroughs occur because of serendipity, which is a random disruption thus impossible to predict.
