Novel quantum dots facilitate coupling to quantum memory systems

Researchers at the University of Basel and Ruhr-Universität Bochum have realized quantum dots--tiny semiconductor nanostructures--that emit light close to the red part of the spectrum with ultra-low background noise. Quantum dots might one day constitute the basis for quantum computers; the light particles, also called photons, would then serve as information carriers. Quantum dots with adequate optical properties had previously only been obtained for photons with wavelengths in the near-infrar...
