From: Urion on 16 Feb 2010 20:55 What do you think could be the next type of computers, i mean even more advanced or faster than quantum computers? Classical computers even those relying on nanotechnology as do nanoelectronic processors are nothing new because those are still classical computers. Spintronics and optoelectronics could provide faster processors and memories in the future but those are still classical forms of computers. Superconducter digital electronics could provide energy-efficient computers but I think that even those type of computers are still classical. Quantum computers are another big step forward in computation speed and are very efficient in solving some problems like simulating quantum mechanics. My question is: What do you think will be an even more advanced type of computer, even faster and more efficient at solving certain problems than quantum computers?

There aren't any quantum computers. There's theory and a few benchtop demos of "concept."

The DNA computer was cute. Short DNA sequences were the input. You dump in all possible solutions (parallel combinatoric synthesis, no problem), add a suitable polymerase and template, and wait for the answer to amplify itself out of the noise. When you multiply the combinatoric library by molecular weights and turn that into grams, a typical minimally "interesting problem" would require 100 kg and up of unique DNA primers. Add water and that is a big vat with slow kinetics. Then you have the unknown hazards of "processor" disposal. -- Uncle Al http://www.mazepath.com/uncleal/ (Toxic URL!

Current systems are not as efficient as they could be. One major problem in any computer system is error latency (an error getting through the system to an observable point so it can be diagnosed and fixed to avoid bogging the system down with superfluous cycles not used in actually doing the calculation). Code must be run through a system, the outputs examined, and discovered bugs fixed, then the code run through again. Lather, rinse, repeat until ALL the bugs are gone. But there may be a better way : http://www.computer.org/portal/web/top-takes/home/-/blogs/debugging-using-resublimated-thiotimoline;jsessionid=7a70aea780d810b531f3cd336365?_33_redirect=%2Fportal%2Fc%2Fportal%2Flayout%3Fp_l_id%3D777575 Mark L.
