I've attended half a dozen webinars held at work on quantum computing. IBM has been in the lead for several years. I think the author of that article doesn't understand a LOT.
"While a qubit can hold multiple values at the same time, it is burdened by an inherent problem. When researchers try to read the information stored in a qubit, it “decoheres” and collapses into a classical bit that holds only one value: a 1 or a 0.
This means that if someone tries reading a qubit, it loses its basic power. So scientists need to overcome an essential problem: How do you build a computer if it breaks whenever you use it?"
That is garbage.
