this is absolutely wild!

being able to transfer entangled quantum states across existing fiber-optic cables is a game-changer.

There's a lot of interesting things you can do with entanglement and tweaking the phase of qbits if you have access to a quantum computer (like IBM and quikset).

But I didn't think much of it because you had to physically transfer the state of your qbits over a distance, which at the time was not possible except for space lasers.
