Photonic quantum networks a step closer thanks to on demand single-photon sources
Colloidal semiconductor nanocrystals, also known as quantum dots, have emerged as excellent materials for applications ranging from imaging to light-emitting diode (LED) displays and lasers. Thanks to quantum confinement, quantum dots become non-classical light sources that emit photons one by one. For practical applications, single-photon sources that can be electrically excited and controlled are highly desirable. This calls for complex fabrication tools and methods for device preparation. The EU-funded NANOLED project aims to develop LEDs based on individual colloidal nanocrystals using promising material platforms. Project results are expected to shine light on a pathway for the development of quantum light sources for practical quantum information applications.
