Serious Quantum Excitement With Entanglement Transfer!

Posted by Scott Holstad on September 3, 2019

Okay, my quantum (and other physicist/scientist/researcher/etc.) friends and colleagues. I’m sure some of you know this and may already have read the paper, but if not, get ready! We all know that while people are working hard in/on quantum computers, there’s still a world of difference between that and a quantum Internet. Entanglement. Quantum information can’t be copied and transmitted over a traditional network. Quantum particles require a different interface, allegedly. However, Austrian researchers led by Ben Lanyon have successfully completed a documented unreal experiment: They were essentially able to transmit quantum entanglement 50 km over basic fiber!

The paper discussing this experiment was published August 27, 2019 and you can find it at “Light-matter entanglement over 50 km of optical fibre.”

 

Caveat: For those less familiar with quantum research, the paper might appear to be fairly technical, but not overly so for many, I believe. Graduate level and above quantum physics. Don’t get mad at me if I turn out to be wrong. Quantum’s not for everyone…
