Questions: Multi-particle entanglement, speed of light, electron orbitals

[MDH72]

1. As well as an entangled pair of electrons, particles, photons or whom ever is buddied up, are there entangled triplets? Quadruplets?
2. Is it generally accepted that electro/magnetic waves travel at c, dependent upon the medium of course?
3. What is a nominal time period of one orbit of the electron of a hydrogen atom? Or, perhaps there is no formal "orbit" and the electron entangles or tag teams its pair to show up at the proper point and hopefully satisfying known equations with which to do the required calculations.
4. In the image, the author should replace the word literally with figuratively, IMO.

A quick Google should shed some light on these questions. What has your research turned up?

1. As well as an entangled pair of electrons, particles, photons or whom ever is buddied up, are there entangled triplets? Quadruplets?

Yes. Just about any system of multiple interacting particles will be entangled in some way.

2. Is it generally accepted that electro/magnetic waves travel at c, dependent upon the medium of course?

It’s more than “generally accepted”, it is true by definition: the meter is defined to be the distance that light travels in 1/299792458 seconds.

3. What is a nominal time period of one orbit of the electron of a hydrogen atom?

Right, electrons do not move in orbits around the nucleus. But…

Or, perhaps there is no formal "orbit" and the electron entangles or tag teams its pair to show up at the proper point and hopefully satisfying known equations with which to do the required calculations.

Not clear what you mean here. There’s only one electron in a hydrogen atom, and its behavior is described by Schrodinger’s equation.

4. In the image, the author should replace the word literally with figuratively, IMO.

It’s hard to say without more context, but the wording of the caption suggests that the image did not come from any serious publication.

Can somebody edit the title for a more descriptive one?

The quantum computers use networks of entangled qubits.

The quickest way to get someone to take a look is to report the thread, but now that I've seen this post from you I can take care of it.
