"For the first time, the polarization state of a single photon produced by one quantum dot has been successfully transferred to another quantum dot located at a separate physical location. In simple terms, this means the properties of one photon were transmitted to another through quantum teleportation.
The demonstration marks an important step toward practical quantum communication networks. During the experiment, researchers used a 270-meter free-space optical link to connect the systems. The findings have been published in the journal Nature Communications."
I have a special interest in this topic.
Many years ago, I found out about the measurement problem. It blew my mind. I told my housemate at the time that I wish I could talk to somebody who could explain it to me.
Two days later I met this guy...
https://de.wikipedia.org/wiki/David_Deutsch_(Physiker)
...who is the author of The Fabric Of Reality and plays a major role in developing the many worlds interpretation of quantum mechanics.
It was a was a total chance encounter but I ended up chatting to him for about two hours. I'm sure he was as intrigued by some random guy asking him to explain the collapse of the wave function as I was that somehow the universe had put this guy in front of me. To this day it remains the most synchronous encounter of my life.
Anyway, during the conversation he explained to me how he had been working on quantum encryption - a super interesting topic if anyone cares to ChatGPT it. And since then I've tried to stay up to date with progress in quantum communication. And now it appears to be a reality.
Basically, no latency and zero interference regardless of obstacles or distance. Also entirely immune to interception, which was what David was working on.
...this could render Starlink entirely obsolete.
