Experiments generate quantum entanglement over optical fibres across three real cities, marking progress towards networks that could have revolutionary applications.

A quantum internet could enable any two users to establish almost unbreakable cryptographic keys to protect sensitive information

We can already do that dumbass.

Ah, finally. Now we will stop talking about, hearing about, and shoving "AI" in everything and the next new thing will be "quantum internet enabled" things.

Your statement isn't terribly we informed

[–] [email protected] 1 points 4 months ago (1 children)

I mean they're not wrong, we already have encryption algorithms resistant to quantumn computers.

That's not what the article was about

I'm sorry. I realized in a comment below that one its very useful for governments/militaries and corporations.

[–] [email protected] 7 points 4 months ago (1 children)

I guess that's far more unbreakable than what we have. But anyway, several three letter agencies will fight this (again) tooth and nails.

This will be useful for militaries and corporations, not consumers. If it can't work anywhere (or over a VPN, or wirelessly, etc.) It won't work.
