Steane is best known for his work on quantum error correction, fault tolerance and ion trap quantum computing, which may not engender a lot of confidence in his foundational speculations. However, the abstract looks interesting and the final sentence: “A single universe undergoing non-unitary evolution is a viable interpretation.” would seem to fit with my “Church of the smaller Hilbert space” point of view. Steane has also addressed foundational issues before in his paper “A quantum computer only needs one universe”, and I like the title even if I am not familiar with the contents. Both of these are on my reading list, so expect further comments in the coming weeks.

Humor that appeals directly to quantum physicists: priceless. I am greatly looking forward to the theological debate between members of the Church of the Larger Hilbert Space and Church of the Smaller Hilbert Space. And can we look forward to the Church of the Infinite Hilbert Space, or the Church of the Empty Hilbert Space (that last one feels a little Zen, doesn’t it?) And why aren’t their any Churches for Banach Spaces? Members of all Hilbert Space Churches would be welcome, of course.

I suggest you forget everything you know about it and that should remedy the situation. Hmm, this is a funny case because most people are envious of pure states.
