Physicists couple key components of quantum technologies

ScienceDaily.com: Nanotechnology News - Wed, 10/09/2019 - 18:32
Researchers are engaged in intensive work on the components of quantum technologies - these include circuits processing information using single photons instead of electricity, as well as light sources producing such quanta of light. Coupling these components to produce integrated quantum optical circuits on chips presents a challenge. Researchers have developed an interface that couples light sources for single photons with nanophotonic networks consisting of photonic crystals which can be replicated by using established nanofabrication processes.
