What does this mean exactly, /sci/? And how "unhackable" is it really?

Also, will this revolutionize global communications?

Einstein said it, pop science will NEVER let it go, spooky is a technical term now.

>>8127755
Current quantum tech is shit, unhackable is meaningless rhetoric that is not actually possible, and THIS in particular will do nothing about global communications, it's a fucking experiment.

google quantum cryptography.
my own poor understanding of it is that due to
>>8127770
>quantum entanglement
It is possible for the receiver of a message encrypted this way to determine if somebody is eavesdropping on the conversation which helps somehow...
>>
>>8127755

Isn't the quantum entanglement thing supposed to communicate faster than light? isn't that way more important than being "unhackable"?
>>
>>8129544
No, you can't communicate with the correlation of entangled particles. You can however use the entanglement to detect eavesdropping.
>>
The only difference is that information is encoded not as signal strength, but as light polarization. The rest (entaglment) is pure bullshit.

Explain all the experimental verification then
