The use of "Internet" in the title and article is deceptive. They did not send data over the Internet, they sent conventional optical data over a 30 mile spool of fiber and quantum entangled photons on an unused wavelength over the same cable in a laboratory setting.
- ko27 2y agoIt's not deceptive. The whole point of the study was to figure out a way to transfer quantum information through active Internet cables, and not empty optical cables.
- fsh 2y agoI find the wording highly deceptive. The main feature making the internet globally scalable is not that it goes through fibers, but that it uses package routing. Nobody knows how to do this with qubits, so quantum communication doesn't scale at all. Instead, the community started doing these publicity stunts with very limited applicability.
- swores 2y agoTheir title is specific in saying "internet cables", not the internet. It seems fair to me that this is one step on the journey, that figuring out going through cables comes before figuring out routing between cables. It's a press release for a specific research paper, not a product release marketed to consumers. (Though it's possible the researchers themselves agree with you & iandanforth more than with me & ko27, as the title of the actual research paper itself doesn't use this wording; it's "Quantum teleportation coexisting with classical communications in optical fiber".)
