"Researchers created quantum dot light-emitting diodes that can produce entangled photons (QDLEDs). The pyramid-shaped quantum dots of the QDLED—as in the same technology behind QDLED TV’s—are electrified using nanotechnology to entangle the photons. It is these pyramidal structures that allow physicists control over the process—something that has been significantly difficult over the years."
It's still a long way to practical quantum computing, but it's good to know we're on the path.
