The lab explores the limits of natural phenomena through quantum information science and precision measurement.
AboutAbout the lab
Pushing the limits of observation by every possible means.
The Physical Information Systems Lab asks how far the limits of observing natural phenomena extend, and studies a wide range of natural phenomena.
In considering the limits of information processing, the lab holds that it is necessary to clarify what can be done, and how, under constraints, and it regards quantum information science and precision measurement science as its means of doing so.
Undergraduate students at the University of Tsukuba are accepted for graduation research from the College of Information Science in the School of Informatics.
Graduate students apply to the Degree Program in Information Science and Engineering in the Degree Programs in Systems and Information Engineering.
Key terms
- Quantum information science
- A field that considers the processing and transmission of information using the properties of quantum mechanics
- Precision measurement science
- A field that studies methods for measuring a target as accurately as possible, and the limits of such measurement
- Quality engineering
- A methodology for designing and evaluating products and systems so that their operation stays stable despite variation and changes in conditions

ResearchResearch themes
Natural science advances by observing natural phenomena, building models from the results, and checking them again through observation. This lab takes up the question "Where are the limits of observation?" and studies a wide range of natural phenomena by every possible means.
*Illustrative imageExploring the Limits of Information Processing
What can be realized on Earth is not necessarily all there is, so the lab holds that it is necessary to clarify what can be done, how, and at what scale under constraints. It regards quantum information science and precision measurement science as its means of doing so.
*Illustrative imageAnalyzing the Stability of Quantum Computers
When quantum computers became available on the cloud, the lab set out to build a system that generates ultimate random numbers and noticed that the computer's operation was unstable. It then analyzed the stability using the methodology of quality engineering and presented the results at a peer-reviewed international conference.
*Illustrative imageWhy Can We See the Starry Sky?
Starting from the explanation in an introductory book on quantum mechanics that "the reason we can see the starry sky lies in quantum mechanics," the lab investigated the history of vision and quantum mechanics. It found that the experimental results known so far could not be explained consistently, and wrote a column about this for the December 2023 issue of Suri Kagaku (Mathematical Sciences).
