Welcome to Quantum Science & Technology Lab!

Masao Hirokawa was appointed professor at Kyushu University in December 2018 and established his laboratory in April 2020. As a member of the Cyber-Physical Computing Laboratory, his research focuses on quantum science and technology. Specifically, he conducts theoretical research into the design of quantum programming languages and their compilers, with a strong emphasis on quantum architecture. He also investigates the semantics of quantum programming languages and pursues theoretical studies on quantum models geared toward quantum simulation.
The Hirokawa Laboratory develops quantum-classical hybrid computing systems and conducts research into both their theory and implementation. The slides uploaded here provide an overview of the concepts underlying these systems. This slide deck is from a presentation given at a mini-workshop held in conjunction with an intensive course on the semantics of quantum programs, taught by Professor Mingsheng Ying (University of Technology Sydney) --- a leading authority in the field --- at Kyushu University from September 28 to October 2, 2026.

Our laboratory has developed a system for concealing and restoring physical-layer data. You can find more details here, and its application to audio data here.

The list of research papers can be found here.
