Also from the article: "A quantum computer could also crack the most sophisticated encryption in use today." I think this gives the impression that all encryption methods known today fail in the face of a quantum computer. But this is not true. There are a wide array of "post-quantum cryptography algorithms" [1], or encryption schemes thought to be secure against quantum attacks. I suppose the author might have a particular scheme in mind which he considers the "most sophisticated."
