Researchers at Cork's Tyndall Institute have engineered a way to enable quantum dot LEDs to produce entangled photons, which can be placed where needed, such as on semiconductor boards. This could enable the building of quantum computing at scale much sooner than expected, as the necessary materials are readily accessible. Quantum dots offer many advantages over conventional LEDs, including their ability to operate in two states simultaneously, and they also emit light with an extremely short wavelength.

While not the first to produce entangled photons using LEDs, the researchers built a scalar array using commercially available materials and conventional semiconductor fabrication technology.
