The University of Tokyo, together with the National Institute of Information and Communications Technology (NICT), RIKEN, and NTT, has proposed a “quantum arbitrary waveform generator (Q-AWG)”, which is a light source that outputs any quantum light with a desired pulse waveform.

They have realized a method to freely control the pulse waveform of quantum light, which is a technology. As a result, for the first time, we succeeded in generating quantum light with a special pulse waveform necessary for the operation of a large-scale optical quantum computer, which is currently under development.

By developing a quantum arbitrary waveform generator by expanding the system realized this time, it is expected to become the “ultimate quantum light source” that realizes various quantum technologies such as optical quantum computers.

The greatest feature of Q-AWG is its versatility. By responding flexibly to ever-changing needs, it will be possible to accelerate the development of quantum technology.
