This effort is likely aimed at industrial/academic entities and not "you" as in a single person. But anyway, it needs to be emphasized that the phrase "quantum computer" is today used to mean anything ranging from
-a useless machine that produces a signal indistinguishable from noise TO -a highly sophisticated marvel of science and engineering that performs otherwise impossible calculations
Many industrial quantum computers today fall closer to the the former category than the latter. A single person or small team with minimal funding has basically no hope of building anything meaningful.
I don't know of any other device that has such a broad range of quality represented under one name. Maybe like calling ELIZA and Opus 4.6 both "AI".
All “industrial” quantum computers currently fall entirely in the former category. Anyone trying to tell you otherwise is selling snake oil.
