Not that there aren't enough discussions going on already, I wanted to know what people think about Paul Davies' argument using Seth Lloyd's calculations, concluding that a quantum computer can never be built? I suppose there are people here that believe that the multiverse makes the quantum computer possible regardless of what Davies says, but if so, why?

Here's a post that sums up some of it and provides some links:

Some quick criticisms of Davies' argument can be found in the comments of this blog entry by a physicist working on quantum computation:
