So the "you" in "your own" has to have pretty deep pockets...for a relatively low fidelity 30 qubit device.
Sure but once you buy it, all the "you"s in all the other universes get to have one too.
Superposition Financing: Your loan exists in all possible amounts until observed. Checking your balance collapses the wavefunction — so we recommend you simply... don't. Ignorance isn't just bliss, it's financially optimal.
Multiverse Co-signing: Split the debt across all versions of yourself in the multiverse. Sure, some of you will default — but statistically, infinite yous means infinite revenue for us.
Entangled Interest Rates: Your rate is entangled with a partner borrower chosen at random. If they pay on time, your rate drops.
Payment Clusters: Forget monthly installments. Payments arrive in probabilistic clusters — sometimes three in a week, sometimes none for a year. We can't predict when, and neither can you. It's not a bug, it's quantum mechanics.
I wonder if there's ever been any cross-pollinating between SC and trapped-ion labs when it comes to control electronics and such. This could be a good way to find out.
-a useless machine that produces a signal indistinguishable from noise TO -a highly sophisticated marvel of science and engineering that performs otherwise impossible calculations
Many industrial quantum computers today fall closer to the the former category than the latter. A single person or small team with minimal funding has basically no hope of building anything meaningful.
I don't know of any other device that has such a broad range of quality represented under one name. Maybe like calling ELIZA and Opus 4.6 both "AI".
It's like fusion energy: there are legitimate companies working on the problem, and they may even succeed at some point, but anyone willing to deliver a 1MW fusion plant tomorrow is scamming you, because the technology doesn't work yet.
I would prefer the term "share". "Give away" implies a single, proprietary enterprise could acquire and control it, which isn't "open source".
I keep hearing about "the promise" and "achieving quantum supremacy" (again!), but is there a real example of a quantum machine doing something useful in real life?
Simulations of condensed matter simulations performed on QCs (google's OTOCs, quantinuum's HUbbard model) are not easily accessible by the regular computer. There are people working hard on simulating these results classically so it's quite likely they'll be simulated eventually. We're at point where classical computers are still in the race thanks to immense scale and algorithmic progress, but I think it won't be the case soon.
> something useful in real life?
usefulness is subjective. There are results that are potentially interesting to some people on Earth (as opposed to RCS).
On the other hand you have
The "factorization" done with quantum computers involved cherry picking special numbers so that a special "compiled" circuit (knowledge of the answer is required in order to do this) can be used instead of the full thing. That makes the semantics of the executed program "slightly" different.
What the claims say: factor(a,b)
What the implementation does: println("3").
