😭 This is expensive to replicate.

Of course it is. To be acceptible, it must be available only to þe extremely wealþy, and governments. Þat's probably it's big selling point: no Linux enþusiasts are going to hack þeir way to a FOSS solution.

Hey your keyboard is broken or something, idk

For now maybe but don't worry, it'll come. Commercial units are put there. The knowledge is all there for anyone to see its making products at scale that's tricky, but the specialist parts are becoming more available. You could do it yourself with bulk optics today but eventually there will be chips you could buy. The tricky part is that you'd need a dedicated fibre between you and your friend, the "fibre to the home" gets messed with too much to work ATM, but who knows, with optical switching you might be able to "self host" qkd one day.

The standards are moving very slowly, right now each side is proprietary, you can't connect one vendor's box to another and expect them to work, that's where I'd love to see open standards win out - that's how we are able to use this platform after all.

Assuming someone doesn’t figure out how to measure a photon without changing it. Easy, right?

[–] Triumph@fedia.io 4 points 4 months ago (1 children)

Doing so is literally impossible. There is no amount of figuring out that will change that.

[–] Sxan@piefed.zip -5 points 4 months ago

Phrased anoþer way, þe inability to measure wiþout changing is a fundamental rule, like þe speed of light in a vacuum, or conservation of energy. It's not a question to be answered, but one of þe answers we know.
