Michio Kaku on Quantum Computing
June 12th, 2009
Thanks to Saleem Khan for this question about quantum computing. Hear what Dr. Michio Kaku has to say about it to Dr. Kiki in this quick segment.

A couple of comments.
First of all, Kaku says that the IBM computation was “3 times 5”, i.e. the question was 3 x 5 and the answer was 15. In fact, the computation was “factorize 15”, i.e. the question was what are the factors of 15? and the answer was 3 and 5. Although this computation is still not very impressive, there is a big difference because multiplication is easy to do on an ordinary classical computer, but factorization is believed to be hard.
Secondly, he talks about the “power of silicon”, by which I guess he simply means the kind of technology that powers current computers. However, it is not clear to me that you couldn’t build a quantum computer out of silicon by exploiting it in a different way, so it would be more accurate to say “power of the current way of using silicon” or better still the “power of classical computers”, since it really doesn’t matter what the computer is made out of.
Prof.Kaku in my mind is a great physicist.. and as for that previous statement.. he broke it down for her to understand..if he used a complex equation.. he would have had to break it down anyway.. he just used a simple one to explain it to her easier.. not to impress people watching the vid.. and the way the classical computer is done is starting to become less and less compatable with the upcomeing technology and information.. we are begining to need a more up to date/standerd computer design..in order to store the new information thats emerging from years of progressive and vigerous study and experamentation,not to mention the new ways we are finding we can use a computer..which is way to much for me to mention.By the way Prof.Kaku i admire your work
How exactly do birds perceive the Earth’s EM field via the quantum computers located in their eyes? Also is this only a feature found in migratory birds or in all birds?
