Max Planck Institute Physicists Have Managed to Create a Basis for New Type of Quantum Computer

…In order to effectively use a quantum computer, a larger number of specially prepared – in technical terms: entangled – basic building blocks are needed to carry out computational operations…

…A team of physicists at the Max Planck Institute of Quantum Optics in Garching has now for the very first time demonstrated this task with photons emitted by a single atom…

…The  new method could facilitate the construction of powerful and robust quantum computers, and serve the secure transmission of data in the future…
