Our group was established in Oct. 2019. We study optical quantum computing and its applications.

We accept undergraduate and graduate students of Department of Applied Physics, School of Engineering/Faculty of Engineering. Please feel free to contact Takeda (takeda(at)ap.t.u-tokyo.ac.jp) if you are interested.


Our paper on time-domain beam-splitter operations for a highly non-classical optical pulse is now available on arXiv.
Mr. Takato Yoshida was awarded Shoji Tanaka prize (excellent master’s thesis award) from Department of Applied Physics.
Our paper on the demonstration of a continuous-variable variational quantum algorithm has been published in Physical Review Research.
Our paper on quantum computation with three optical pulses on a unique loop-based photonic quantum computer has been published in Physical Review Letters.
