Yet again, the sky is falling.
Researchers at UCSB have demonstrated a "quantum processor" that correctly operates "Schor's algorithm for factoring primes" all of 48% of the time (Photo left, courtesy of UCSB). This has produced all sorts of dire predictions about existing cryptographic mechanisms.
This is nonsense. We don't know enough about quantum computing to believe that a practical quantum computer architecture can follow Moore's law. And so-called "quantum cryptography" is not the answer.
