Advancements in Quantum Light Sources and Theories for Future Technologies

MIT researchers have discovered that photovoltaic nanoparticles can emit streams of identical photons, potentially paving the way for new quantum computing technologies and quantum teleportation devices. The device emits a stream of single photons and could provide a basis for optical quantum computers. The researchers used novel materials that have been widely studied as potential new solar photovoltaics and showed that nanoparticles of these materials can emit a stream of single, identical photons.
