An anonymous reader writes "Researchers at Purdue say the merging of plasmonics and nanophotonics is promising the emergence of new 'quantum information systems' far more powerful than today's computers. Plasmons are quasiparticles that combine electrons and photons. And by using them in place of the simple electrons of today's computers, they could overcome limitations in the operational speed of conventional integrated circuits. The technology hinges on using single photons for switching and routing in computers that would harness the exotic principles of quantum mechanics.'"
