A joint research group led by Professor Akira Furusawa and colleagues from Nippon Telegraph and Telephone (NTT), the National Institute of Information and Communications Technology (NICT), and RIKEN has successfully developed a method to control the pulse waveform of quantum light at will. This has made it possible for the first time to generate quantum light with the special pulse waveform required for the operation of a large-scale optical quantum computer. If the system realized this time is extended to develop a quantum arbitrary waveform generator, it is expected to become the “ultimate quantum light source” that will contribute to the realization of various quantum technologies, including optical quantum computers. The paper was published in the online edition of the American scientific journal Science Advances on October 28.
