A lab that uses tiny superconducting devices to trace the sources of nonequilibrium quasiparticles.

The lab studies devices built from tiny junctions, such as Josephson junctions and single-electron devices. It has developed a highly sensitive method for detecting phonons using a single Cooper-pair transistor. Using this detection method as its main tool, the lab tackles the problem of where nonequilibrium quasiparticles in superconducting electrodes come from, which is one of the major causes of decoherence in superconducting qubits.

A lab that takes on challenges in energy and social infrastructure through AI and quantum research.

The lab conducts research toward realizing a carbon-neutral society. It works on developing next-generation energy devices using AI, optimization problems for social infrastructure systems, and algorithms for quantum computers. Its main research areas include reinforcement learning, machine learning, stochastic optimization, quantum algorithms, and quantum circuit learning and quantum machine learning. The lab is also building a physical quantum computer system based on superconducting qubits.

A lab aiming at new information processing through superconducting and single-electron devices.

The lab studies electronic devices and circuits that use superconducting and single-electron phenomena, as well as physical reservoirs made of nanoparticles. Focusing on devices that move flux quanta or electrons one at a time, it performs circuit simulation, device fabrication, and measurement of electrical characteristics. The lab works on research themes that lead to novel information processing systems. It also collaborates with the Quantum Future Creation Device Development Center.

The lab works on nanostructures such as quantum dots and on optoelectronic devices.

The Kaizu Lab shares a website with the Yamaguchi Lab and the Miyashita Lab and carries out its activities jointly with them. According to the research overview on the website, the Yamaguchi-Miyashita Lab fabricates nanometer-sized materials and studies their properties, conducting basic research that leads to the development of new next-generation optoelectronic nanodevices. The central theme is the quantum dot structure, which confines electrons and holes in three dimensions. In addition to how to fabricate quantum dots and quantum nanowires and how to evaluate their properties, the site also covers applications such as semiconductor lasers and solar cells.

The lab explores the birth of stars with radio telescopes and develops its own receivers.

The Sakai Lab develops receivers for radio telescopes and uses them in observations to study how stars are born. In particular, the lab aims to clarify how massive stars, which have at least eight times the mass of the Sun, are formed. The lab not only observes with existing instruments but also mounts instruments it has developed itself on large radio telescopes for observation. Star-forming sites are cold and cannot be seen in visible light, so the lab studies them by observing radio waves.

The lab does machine learning research on learning from imperfect real-world data.

The Kohjima Lab studies machine learning that can learn from real-world data that is insufficient in both quantity and quality. The lab aims to expand the areas where machine learning can be effective and to improve the performance of AI systems. This is an NTT collaborative lab. The faculty member belongs to Nippon Telegraph and Telephone Corporation and conducts research in cooperation with Professor Minami. For students who wish to take part, the lab would like to create opportunities to experience corporate research activities, such as internships at NTT laboratories.

A lab that integrates machine learning with knowledge representation and reasoning to build trustworthy AI.

The Inoue Lab works to build explainable, robust AI by integrating machine learning and knowledge representation and reasoning, which have long been studied separately in AI research. Going forward, the lab plans to also use the commonsense knowledge of large language models (LLMs) and apply it to advanced intellectual tasks. The research is carried out at the National Institute of Informatics. Students in the lab are given a seat at the National Institute of Informatics as collaborative graduate students, and can use the institute's computing environment and the generative AI models it develops. Students can join this lab from the graduate level.

A lab that uses machine learning to analyze data on human activity and understand people.

The Orihara Lab, a Kioxia collaborative lab, studies the analysis of the many kinds of data generated by human activity. Human behavior in cyberspace is increasingly recorded as data, and analyzing it may reveal how people make decisions and what preferences they hold unconsciously. The lab develops machine learning and natural language processing techniques as analytical tools, aiming to understand people more deeply through their access to cyberspace. Students propose research topics on their own initiative and decide on them with reference to the faculty's advice.
