Quantum teleportation of an unknown input state from an outside source onto a quantum node is considered one of the key components of long-distance quantum communication protocols. It has already been demonstrated with pure photonic quantum systems as well as atomic and solid-state spin systems linked by photonic channels. Now, a team of researchers from the Netherlands, Brazil and China has demonstrated quantum teleportation of a polarization-encoded optical input state onto the joint state of a pair of nanomechanical resonators.
“The use of optomechanical devices is a breakthrough because they can be designed to operate at any optical wavelength, including the low-loss infrared telecom fiber wavelengths,” said Dr. Simon Gröblacher, a researcher in the Kavli Institute of Nanoscience and the Department of Quantum Nanoscience at Delft University of Technology.
“It is this wavelength that results in the lowest transmission loss, allowing the longest distance between repeater nodes.”
“This milestone was possible due to the quality and flexibility of our nanofabricated optomechanical systems, which, unlike most other quantum systems, allow for independently engineered optical properties. A future quantum internet will undoubtedly make use of the existing telecom network at this wavelength.”

Instantaneous communication via fiber optics?

Teleportation? Sounds like data transfer to me.
I love the story in Michael Crichton’s timeline. They explain that they accidentally invented quantum teleportation, however they found they were transmitting objects through quantum foam into an alternative universe and a different time. He offered a simplified explanation of quantum physics and the interactions of alternative universes with our own. Amazing theory.
Just another decade and we’ll have the ansible!
how far apart are the transmitter and receiver ?
The guy messing around with this needs to be careful with the Admiral’s beagle.
We have TV, and now we’re talking about TP. I don’t believe I’ll be around to buy my first TP.
(Yeah, I hear you; TPs were invented by American Indians).
In other news LSD was created in the 40’s.
This couldn’t have happened without the advances in disfronificator technology. .
And in other news, I need than I got or I’m on a phantom thread.
Wake me when they announce we’ve tapped into the fully-entangled Galactic Internet.
You ain’t seen nothing until you’ve seen alien XXX
Of course, then the plot of the book would never have happened. Time travel in fiction always gets messy.
... Notice how Americans aren’t on these teams of researchers anymore? I’m sure they remain on many, but I haven’t seen any in the articles I’ve stumbled across.
Maybe because diversity is “strength”?
Words mean things. It's disgronificator.
LOL. That’s what I thought too. 👍😀🤗😃
If this experiment mimics the process of photonic quantum teleportation then it still requires the transmission of the unknown qbit via a classical channel. There is no way around the speed of information only that a bit in one place can be detected via a Bell-State Measurement whose state is mutually dependent on an entangled pair. This is interesting but not very useful in any computationally relevant informational way.
