Since there isn't a usable pure quantum computer yet, due to a low number of qubits, that claim is nebulous. Currently commercial quantum computers are hybrids. The pure ones are still being developed. We have yet to see if they're really as unhackable and great as claimed. I believe in global warming more than I believe the claims of researchers that tell us how wonderful future quantum computers will be, with absolutely no evidence presented or meaningful comparisons to far more cost effective conventional, and normal room sized, super computers.
