I'm curious to know if it's useful to study Feynman article "Quantum Mechanical Computer" nowadays. I'm a computer scientist, and i don't know any of the literature in quantum computers. Since long time has passed from 1985 it's a waste of time studying that article? If yes, why?

The article can be found at: http://www.cs.princeton.edu/courses/archive/fall05/frs119/papers/feynman85_optics_letters.pdf

Thanks.

It's at least amazing how deeply into technicalities Feynman actually went. At the same moment, I believe that all more modern introductions contain everything from this Feynman article that remained viable. –  Luboš Motl Mar 29 '13 at 9:11

The mentioned article by Feynman and the lectures he gave around the same time are still relevant. The approach followed by Feynman still informs how physicists woking in the field look at computation.

That said, notably missing in the article is the computer-science perspective on the field including, but not restricted to, ideas of thresholds for universal quantum computing, quantum computational complexity in the polynomial hierarchy and quantum communication.
