Future Computers Throughout his life, R. P. Feynman was intensely interested in the language spoken by nature. His parton picture is one of the prime examples. He was of course interested in the language of quantum systems. Click here for a photo of feynman's bed-room laoboratory when he was 13 or 14 years old.
According to the computer chronology, the human race has been and still is interested in harnessing the intelligence which can be generated from devices other than brains, such as abacus, slide rules, and electronic circuits. In order to harness their intelligence, we have to learn the language they speak. Slide rules can perform additions, and vacuum tubes can say Yes or No. We can translate the addition performed by the sliderule to multiplications if we use logarithm. The vacuum tubes can perform binary logic.
As for quantum computers, we are still interested in what language quantum systems speak and how to translate it to a computational language useful to us. This is quite consistent with human instinct, and many physicists are working on this subject these days.
If we are going to build quantum computing hardware, we have to use optical circuits, as electronic computers use electric circuits containing capacitance, inductance, and resistance. Optical circuits will contain polarizers, lenses, filters, interferometers, laser, and layers. We should also understand the language spoken by these optical devices.

These day, the Lorentz group is becoming the basic language for optical sciences. It is well known that the underlying language for quantum optics is the Lorentz group. How about classical ray optics? I have been writing papers on this subject for sometime. Everybody knows how to focus manual camera. Did you know that your camera is performing contractions of Wigner's little groups?
If optical circuits are useful for quantum computers, it is great!
If not, it is still fun to do ray optics. Why can we not develop
optical computers? In either case, optical devices speak the

We all know that God created light waves, photons, and the media
through which they propagate. God used a rainbow to tell Noah
how people will not be punished. Beautiful story!! What
language did God speak then? The Lorentz group of course. I
studied the Lorentz group to talk with God. In order to show you
how eager I was to speak to God, I would like to show you the
