Pristine Quantum Light Source Created at the Edge of Silicon Chip (ieee.org)

This seems really fundamental to QM research and computation. If only because QM is often explained, at first (almost always?), in singlular particle interactions.

"Pretty much"?

Please don't pick the dumbest-sounding thing you found in an article to start an HN thread with. Other than a cheap hit of oneupmanship, it adds no value, and it's likely to lead to a dumbed-down discussion.

Sorry. I understand. I will refrain from doing so in the future.

Also, the very next sentence uttered by the scientist makes this into a very reasonable statement.

"But unlike a light bulb, there are some sources that actually emit light, one photon at time, and this can only be described by quantum physics."

Single photon light sources are not, in fact, packed with photons.
