This should do as a primer:
Currently one of the main issues, beyond the many technical challenges and the usual hype and quasi-scams, is that nobody really knows how to write quantum algorythms, what can they do, or why should we bother. IBM literally grants anyone free access to their prototypes if they just register and write a proposal of an algorythm they would like to try -and give IBM rights on the patent if it reaches so far.
So quantum computing at the moment it’s like “this is a thing. It does things, but we don’t know which ones”.
(Each now and then, news come out about “quantum computer did this or that”, but so far, it’s been ordinary computing with a quantum computer mixed in for no other reason than saying “quantum computer did this”)
