It looked like just another conference call. A panel of suited men sat at a table, large white name tags and water bottles before them. The man in the center, illuminated by fluorescent lights, spoke to a camera in front of him.
[...] The mics, cameras, and screens made for a seemingly ordinary—maybe even boring—meeting-by-telepresence. But behind the scenes, physicists were encrypting the videostream using arguably the most secure technology in existence. Bai and his colleagues were participating on the first-ever intercontinental, quantum-encrypted video conference.
And on Friday, the Chinese and Austrian researchers who engineered the call published how they did it in Physical Review Letters. Led by physicist Jian-Wei Pan of the University of Science and Technology of China, the team relied on networks of optical fiber, a handful of encryption algorithms, and a $100 million satellite that China launched in 2016—the only one specifically designed for quantum cryptography. "They've demonstrated a full infrastructure," says Caleb Christensen, the chief scientist at MagiQ Technologies, which makes quantum cryptography systems that connect a small number of users. "They've connected all the links. Nobody's done that with [quantum encryption] ever."

My point, perhaps very weakly stated, was that the entire Earth has only a few people who can make advances in quantum theory. The current body of theory does not support implementation and the current implementation fits and starts do not inform theory. In this environment, skepticism is the appropriate first response to any claims. Not malice. Not blind acceptance.

Agreed. With both the characterization of your point and the normal expected reaction.
(normal reaction that I think is inclusively applicable to the assertion of "the entire Earth has only a few people who can make advances in quantum theory." - as such, is a "argumentum ad verecundiam" with a lightweight presence for the "authority making the assertion". But I'll admit I don't have enough time to properly check this assertion).
