“Should be theoretically possible” - I’ll believe it when I see it. Anything quantum is always littered with qualifiers that “this isn’t possible now but the math checks out!” and hand waves potential issues.
Every few years I do a deep dive to learn that nothing has really changed, and the machines still have some fundamental limitation that nobody has solved for how to scale them to a useful # qubits.
- MattPalmer1086 3y agoI'd argue that a lot is changing, but it's a hard thing to do. We have processors with hundreds of (noisy) qubits. We have error correction schemes (that are not realisable yet though). We're exploring multiple different approaches to qubits, from superconducting ones to topological qubits. I don't think I've seen any hand waving of potential issues by anyone. Everyone acknowledges it is hard. Is your complaint simply that it's taking a long time? Or can you point me to some of the "hand waving" claims you refer to?
