The specific type of quantum computer D-Wave has developed can-not solve cryptography problems.
This has nothing to do with Bitcoin.
This.
D-Wave so called "quantum computers" do
not use the quantum entanglement property, thus they can't break public key cryptography.
They call them "quantum" because they use atoms for computation - that's all.
Don't get confused by their marketing team who are obviously taking advantage of the terminology, perhaps to attract naive investors?
Thanks for the insight.
