What is the breakthrough? There is no mention of the problem solved, nor the accuracy of the quantum solution, nor the amount of classical computing resources needed for a non-quantum solution.

The engineering probably has some cool novelty: 39 qubit and 10 million layers is a very large circuit. But simulating a large circuit is very different to achieving a quantum computing breakthrough in CFD.

This press release is uncomfortably close to the border between misleading and fraudulent. It's fairly harmless hype I guess, but claiming a breakthrough involving the world's largest quantum circuit when no quantum circuit has been built is just horrible. I'm not sure I could write this kind of stuff with a good conscience. Rolls-Royce and Nvidia are great companies who are genuinely innovative, it must be awful for the employees who work on the real innovations to read this stuff.

Ok, so I'm not sure what here _really_ benefited from a quantum computer.

I recognize that most folk on HN are concerned about QC applied to exact solutions (which realistically just means breaking crypto), but I'm more interested in QC for analog problem solving.

A real issue you have with digital computers is that they are fundamentally discrete. This means emulating or simulating analog systems (aka the real world) devolves to re-running the same simulation innumerable times and then basically averaging them. The benefit of a QC is that you _should_, in an idealized world, require many fewer runs to get an accurate final representation of the result.

If you go to YouTube you can find many examples of analog computers - often artillery and similar - and I think QC have the potential to offer some real gains in scientific computing by making it possible to create programmable analog computers which haven't really existed in the past.

This press release is simply there to prop up the ISC '23 conference and participants and research projects there. Really don't know if its a good way of doing that.

TLDR - this is being run on GPU's to "prepare for the quantum future".

I am a complete noob w.r.t. Quantum computing, but how exactly does Quantum computing help with Computational Fluid Dynamics? Isn't CFD an issue of efficient parallel computation and scaling of computing resources?

5 years ago we were on the verge of a working, scalable quantum computer. After 5 years of "breakthroughs" we are now about 10 years away from such a device. And any company who associates themselves with this vapourware crap just looks fraudulent...

Where is the generative CAD design tool with constraints??
