Scalable, universal quantum computer? Quantum information processed with system comprising optical photon and trapped atom |
April 10, 2014
When it comes to recognizing complex patterns or to decoding encrypted messages, conventional computers reach their limits. A whole new quality in the communication and processing of data is expected from a technology that exploits the special properties of quantum particles such as superposition and entanglement. Scientists around the world pursue a variety of different concepts towards the development of such a quantum computer. One professor follows the strategy of combining two rather dissimilar techniques: quantum communication using photons, and information processing using stationary atoms. His team has now for the first time realized a quantum logic gate between a single photon and a single atom.
