Optical Processors Light the Path to Warp-Factor Computing

Data has been sent across wide-area networks as light pulses for decades, but optical (or photonic) computing has been slow to meet the challenges of moving data in the form of light at the processor level: photons have proved profoundly trickier to traffic than electrons. And while conventional data processing continued to get faster year-after-year, there seemed scant incentive for technologists to crack the optical conundrum.

No Clunky Magnets or Cryogenics Needed With This Potential Quantum Information Processing Technique

Scientists have generated circularly polarized light and controlled its direction without using clunky magnets or very low temperatures. The findings, by Nagoya University researchers and colleagues in Japan, and published in the journal Advanced Materials, show promise for the development of materials and device methods that can be used in optical quantum information processing.
