I wasn’t at Quantum Information Science Workshop in Vienna, VA, but I heard that the topic of quantum computing “going black” came up at least a few times. One speaker mentioned during his talk that several of his former graduate students were now in “the black hole” of secret U.S. research programs and another expressed, during the open session, that the field is not yet mature enough to be conducting secret research.
Quantum computing is an odd field when it comes to secrecy. Since one (not the only) reason that quantum computers are interesting is that they break the most popular public key cryptosystems, there is a strong national security issue at stake in building a quantum computer. On the other hand, the cat, so to speak, is very much out of the bag, so that it’s not like you can protect the intellectual idea behind quantum computers. But to counter this, suppose that you came up with a surefire way to build a large quantum computer. Should that technology be classified?
There is, of course, only one way to answer this question. A poll, of course:
