Light from the Nanoworld Paves Way Towards Optical Quantum Computers
(TechExplorist) Physicists at the Technical University of Munich (TUM) have successfully placed light sources within an atomically thin material layer with a precision of just a few nanometers. This new method could have a multitude of applications such as quantum technologies, from quantum sensors and transistors in smartphones through to new encryption technologies for data transmission.
Julian Klein, a lead author of the study, said, “This constitutes a first key step towards optical quantum computers. Because for future applications the light sources must be coupled with photon circuits, waveguides, for example, to make light-based quantum calculations possible.”
Previous circuits on chips depend on electrons as the information bearers. Later on, photons which transmit data at the speed of light will be able to take this task in optical circuits. Quantum light sources, which are then associated with quantum fiber optic cables and finders are required as essential building blocks for such new chips.
