Professor Akira Furusawa (Graduate School of Engineering) and his colleagues have succeeded in demonstrating the heart circuit that leads to a large-scale optical quantum computer. The core circuit efficiently generates various quantum entanglement of light with a minimum number of optical circuits, and if it is expanded, large-scale quantum computation with more than 1,000 steps will be possible. The resultant paper was published in the electronic edition of Science Advances on May 17.
