An international research group led by Professor Akira Furusawa (Graduate School of Engineering) has succeeded for the first time in generating two-dimensional clustered states capable of performing large-scale, general-purpose quantum computations. By employing a time-domain multiplexing technique, they have achieved a large-scale quantum entanglement of 25,000 optical pulses and found that it is possible to perform arbitrary quantum calculations with five inputs and 5,000 calculation steps. The paper has been published in the electronic edition of the American scientific journal Science on 18 October.
