She discusses the possibility of breaking encryption codes with Charles Bennett, of the IBM Watson Research Center, in Yorktown Heights, New York.
Bennett says in the article, “I believe it is a sound result that quantum cryptography would not work in this world…. You might say it is a weakness of quantum cryptography—but if there were wormholes, people could go back in time and do worse feats of mischief than reading secret messages.”
For the online Science News article, go to “Take the time to break quantum encryption”—hopefully it is available without a subscription.
Learn more about quantum encryption at the Scientific American’s article “Best-Kept Secrets” and Physics World’s “Key to the Quantum Industry.”
So, can quantum encryption be broken with worm holes? Well, according to Charles Bennett, wormholes may not even exist.
Bennett states in the Science News article that the existence of wormholes “… is not totally impossible, but it is pretty damn unlikely.”
