Stopped 2019 apparently. Shame. We need something to be upstreamed!

It is hard to beat the list present at Quantum computing report: quantumcomputingreport.com/players/.

The much less-complete Wikipedia page is also of interest: en.wikipedia.org/wiki/List_of_companies_involved_in_quantum_computing_or_communication It has the merit of having a few extra columns compared to Quantum computing report.

Tinker Tailor Soldier Spy:

They put a lot of expensive equipment together, much of it made by other companies, and they make the entire chip for companies ordering them.

Contains several computer vision models, e.g. ResNet, all of them including pre-trained versions on some dataset, which is quite sweet.

Fixed quantum angular momentum in a given direction.

Can range between $\pm l$.

E.g. consider gallium which is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p1:

The z component of the quantum angular momentum is simply:so e.g. again for gallium:

Note that this direction is arbitrary, since for a fixed azimuthal quantum number (and therefore fixed total angular momentum), we can only know one direction for sure. $z$ is normally used by convention.

Can be approximated with a diaphragm.

Organelle that is only present in prokaryotes.
