Couldn't find any cost estimate, but from https://openquantumdesign.org/the-quantum-computer (scroll down to "What's Inside") I'm guessing 100's of k$ for the bill of materials (let alone keeping the thing going.)

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.

And yet they won't split the bill with me. Bunch of freeloaders.

Banking Company LLC presents: Quantum Loans™ "Your money is simultaneously yours and ours until you check your balance."

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.

The real joke here is how close these quips are to the reality of modern day financial markets. Specifically, lending and hedging, are time entangled and value within the markets exist in superposition.

Most of the cost is in overpriced laser systems; if that gets solved a trapped-ion system could be reproduced for few tens of thousands of USDs. Still not a hobby weekend project, but certainly more attainable for more universities.

I was gonna say, at that price the cost in a University setting would be nothing in terms of the experience and teaching/learning opportunities provided. Game changer in terms of scaling education which bodes well for the future

Okay so not a weekend project.
