Silicon Chip Produces Tunable Photon Pairs
SAN DIEGO, Calif., Dec. 17, 2014 — A silicon photonic chip that emits entangled photon pairs in a controlled fashion could one day enable quantum transceivers. Developed at the University of California, San Diego, the chip is pumped by a telecommunications-grade low-power diode laser. Through a filter, the chip produces two daughter photons for each pair of photons it absorbs. One of the daughter photons will have a higher frequency than the input photons, and the other will have a lower frequency; their total frequency...
