Most actors in the quantum computing industry are very large hi-tech organiations such as IBM, as well as several govermental agencies across the world.

As of 2023, quantum computers are extremely expensive and difficult to program. So far, not much as been achieved. To sum up, QC has not lived up to its expectation.

Concerning how these machines are made, how they work etc; is irrelevant. Things are so abstract and so far away from the real world. Concepts such as "superposition" have no real meaning, if at all.

The bottom line being that these computers will be able to do unbeliable things, but the technologie is far from being mature yet: scientists barely know what they do, and do not understand much of the very few things they manage to implement.

Taking into account your first question, I assume that your knowledge about QC is not optimal yet.

I would advise one of the following option:

1. I can answer your specific question as it is.
2. I can retrieve an overview of the whole subject; you will then be able to be more specific in your queries.

Which option would you like? Feel free to provide any additional data.
