This milestone marks the first-ever quantum satellite communication link established in the Southern Hemisphere.

minus-squarerottingleaf@lemmy.worldlinkfedilinkEnglisharrow-up2·16 days agoI’ve read some weird paper about such an analog channel, where something quantum on both sides was used to create another analog signal used kinda as an encryption key. Stumbled upon it trying to understand some things about optics long ago.
