The real story isn't the $2B. It's that the foundry is standalone, so other quantum hardware companies can use it. Shared infrastructure beats nine separate research cleanrooms.
I've been out of the space for a bit. IBM has been betting on the engineered superconducting approach, which makes sense given their background, but there are other options, often for potentially different problem areas. Need to dive back in.
There is high agreement on what the real applications of Quantum computing are. Unfortunately these projects are basically useless when it comes to them.
Can you clarify? Do you mean that superconducting qubits are unable to perform the "real applications" theoretically, or that superconducting qubits at the scale this foundry could produce will be unable, or that superconducting qubits that will foundry could produce will still be outperformed by classical techniques?
I mean, we are no where near the scale [qubit count] & quality where the applications apply. Not just this foundry but in general. I suppose the point is to eventually get there, but we are not close yet.
You should still view anything Quantum as early R&D.
The article talks about IBM spreading bets to other techniques. Reminds me to ponder again. Has Microsoft retracted their sketchy quantum claims about inventing new states of matter in the past year? https://www.theregister.com/on-prem/2025/03/12/microsofts-qu...
I'm surprised it has zero mention of potential advantages of trapped ion despite being superior on stability windows, accuracy, and operating temps.
I also appreciate the disclosure about AI generated content, but this article gets too repetitive.
