Mini-satellite paves the way for quantum messaging anywhere on Earth

Quantum key distribution is a real thing. It's a very specific set of constraints that would make it generally attractive, though, namely not relying on networks of trust to function, maybe? Key distribution as a dumb pipe.

I'm not asking if it's "a real thing". I'm asking if it's used anywhere, either commercially or -- in any case -- to encrypt actually sensitive data outside of tech demonstrations. I'm not aware of anything. China has a "qkd backbone" but if they're actually using it for anything is anyone's guess.

This seems like a really dumb thing to emphasize for marketing ends outside of actual competency. But what else is new!

I'm having trouble parsing your comment... What is a dumb thing? Who is emphasizing what?

Ah, understandable.

> what is a dumb thing?

Emphasizing quantum key control. In the situations where it's really relevant you don't need buy-in from investors, the value is evident.

Sayonara!
