WebMar 27, 2024 · As mentioned in an earlier question of mine, I am interested in using type one spontaneous down conversion (SPDC) in optical quantum computing. However, SPDC is a somewhat low probability occurrence - most of the photons pass straight through the crystals unentangled. What methods, if any, are there to improve the probability of down … WebThe highly efficient antireflective down-conversion Bi-doped Y 2 O 3 films have been deposited on the (100) oriented Si and quartz substrates by rf reactive magnetron sputtering using a metallic target. The effects of the Bi doping concentration on the optical and structural properties of the films were studied.
