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.

It was first applied to … See more The newly observed effect of two-photon emission from electrically driven semiconductors has been proposed as a basis for more efficient sources of entangled photon … See more In a commonly used SPDC apparatus design, a strong laser beam, termed the "pump" beam, is directed at a BBO (beta-barium borate) or lithium niobate crystal. Most of the photons continue straight through the crystal. However, occasionally, some of the photons … See more SPDC allows for the creation of optical fields containing (to a good approximation) a single photon.
