Scientists open a new window into quantum physics with superconductivity in LEDs

Scientists open a new window into quantum physics with superconductivity in LEDs: When a layer of such superconducting material is placed in close contact with a semiconductor LED structure, Cooper pairs are injected in to the LED, so that pairs of entangled electrons create entangled pairs of photons. The effect, however, turns out to work only in LEDs which use nanometre-thick active regions – quantum wells.
