What exactly are they trying to accomplish? The article talks about sending entangled photons down a fiber optic… but that just sounds like ordinary fiber with extra steps.

I’m guessing for quantum cryptography. It would allow you to have perfect crypto (assuming the non quantum hardware isn’t hacked (a big if)).

You can have post-quantum cryptography using classical computation, though

(“Simply” pick a problem with no quantum acceleration. I think Elliptic Curves Cryptography works, but I’m not an expert)

You can break elliptic curve cryptography with quantum computers. Post-quantum cryptography is instead based on something called the lattice problem, sometimes called lattice-based cryptography.

Quantum crypto is different than cracking encryption with a quantum computer. The point of quantum crypto is that the key exchange is perfectly secret. If it is observed, the people exchanging keys will know due to entanglement bs that I’m too dumb to understand.

But you basically get the perfect uncrackable encryption of one time pads without having to manage one time pads.

Quantum networks allow you to transmit quantum states between physically separated quantum processors.

You can’t just put quantum before random words.

And what’re you going to quantum do to quantum stop me? Quantum suck it, nerd.
