Breakthrough in quantum photonics promises a new era in optical circuits: Method to enable quantum optical circuits that use photons--heralds a new future for secure communication and quantum computing

Researchers have shown that single photons can be emitted in a uniform way from quantum dots arranged in a precise pattern. The team has used such methods to create single-quantum dots, with their remarkable single-photon emission characteristics. It is expected that the ability to precisely align uniformly-emitting quantum dots will enable the production of optical circuits, potentially leading to novel advancements in quantum computing and communications technologies.
