University of Maryland researchers have overcome the challenge of creating multiple identical photons.  Through the use of silicon and infrared light, the team designed silicon loops which enable “many pairs of single photons out of the silicon chip.”  The challenge was in producing photons of nearly identical frequency (color) with different chips.  The loops permitted the photons to travel the edge of the silicon chip, undisturbed, regardless of the imperfections of the chip.  A benefit is the production of the photons at room temperature, no cryogenics needed.  “This could have implications for a variety of fields where light-matter interactions play a role, including quantum information science and optoelectronic technology.”  This report is found at the University of Maryland…
