It seems to me that quantum computing is a lot of hype and very little substance. If they have been building a quantum computer since 1994 and all they can do after 23 years and many millions of dollars is factorise 21, their achievements are less than impressive.
The problems seem to be intractable. It seems to me that for quantum computing to take place electrons or photons have to be in a state of “superposition”. But the moment they interact with anything, and the more you have of them the more likely this will be so, their “wave function” collapses and bang goes the quantum computer. Have I got that right?
Imagine collapsing quantum computers causing multiple pile-ups of self driving cars, financial markets to collapse along with their wave functions, or launching nuclear missiles in a fiery holocaust.
