GS Chandy says: >He should for the moment forget all about 'quantum computers' as the field is still in rather initial stages of conceptualisation:
I don't think that's the case at all. He should pursue what he thinks is interesting right now. That being said, pursuit starts with reading some quality articles about the subject, which clearly he hasn't really done in earnest. Internet forums are not the place to start. he may find out that he is quickly in over his head, which is the universe inviting him to back up a bit. Exactly where he backs up to (if at all) is part of the fun of pursuing things on one's own.
That being said, I had a nice book that explained the Schor Algorithm in easy stages, suitable for a beginner. I can't remember the title however. I see now that the field (in books at least) is very crowded. Its probably a lot harder to separate the wheat from the chaff. Isn't that what library's and librarian's were for? (Back in the stone ages before we all became so smart.)
