Interests

• It's been so long since we began studying the ultra-strong and deep-strong coupling regimes for the atom-light interaction. We can think this interaction to be for controlling qubits by light in the light of quantum simulation.
• We have been making the research on the control of a measuring device with quantum sensor. This is the cooperative research with HITACHI Ltd. A research on the Lock-on Tracking for Noise-Disturbed Target in 2-Dim Space is derived from this cooperative research.
• We are starting to make the study on the modeling of the system of the part from the low phases of quantum compiler to the quantum architecture as well as the study on semantics for some programming languages for quantum computer.
  (⇑Hirokawa hasn't studied these fields since he did for conventional computers at HITACHI a long time ago:p)
• We are interested in the security of the data on the physical layer of the OSI reference model. We have been studying a concealing-restoring system for those data. We released one of its applications. The application is for the ASCII character codes. Here is its demo written in Japanese. The explanation of the demo is here. This research is the cooperative research with Internet Initiative Japan Inc.
