The lab works on quantum information theory and information theory.

AboutAbout the lab
The fields of quantum information theory and information theory.
Prof. Hayashi is a Professor in the fields of information theory, quantum information theory, and quantum networks.
The faculty profile lists quantum information theory, quantum statistical inference, and information theory as topics for the small-group class in the Master's program.
The profile says that, because this is a relatively new research field, students can reach the level of writing research papers earlier than in other fields, depending on their own aptitude and effort.
The faculty profile says that, except in January, Prof. Hayashi is on research leave from Nagoya University and working at Southern University of Science and Technology; Nagoya University students are supervised mainly online within the scope of an academic exchange agreement, and only students who can handle the minimum on their own are accepted.
Key terms
- Quantum information theory
- A field that treats communication, computation, cryptography, and similar tasks using physical systems that obey quantum mechanics as a mathematical theory
- Quantum statistical inference
- Methods for statistically estimating the original quantum state or its properties from data obtained by measuring a quantum system
- Quantum network
- A communication network that exchanges quantum states to transmit quantum information between distant locations

The research field table lists Prof. Hayashi under information theory, quantum information theory, and quantum networks. The faculty profile says that, because this is an applied field of mathematics, it is important to try to grasp not only problems that have already been formulated mathematically, but also the underlying problems themselves that are being treated mathematically.
