'Entangled' LED could help make quantum computer
Researchers in Cambridge in the UK have succeeded in generating entangled photons using electricity alone, with a new device called an "entangled light-emitted diode" (ELED). The device converts electrical current directly into entangled light rather than relying on laser power as in previous technology. The technique could be a practical way to integrate many entangled light sources together on a single chip – something that will be crucial for making a real-world optical quantum computer.
