This is not the first time that LEDs have been made that can produce entangled photons, but the methods and materials, described in Nature Photonics, have important implications for the future of quantum technologies, explained Dr Pelucchi. 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.
