Yasunobu Nakamura, Professor
Quantum & Condensed Matter2 student voices
The Nakamura Lab approaches quantum information science, which aims at new information processing, communication, and high-precision measurement based on the principles of quantum mechanics, from both physics and engineering perspectives. At the core of its work is research on operating electrical circuits made of superconductors at extremely low temperatures, and controlling and observing them as qubits. Using these superconducting quantum circuits as a tool, the lab is also working on manipulating the quantum states of other physical systems, such as the vibrations of nanomechanical devices and magnons in ferromagnets.

Tatsuo Hasegawa, Professor
Semiconductors & Electronic Devices2 student voices
The Hasegawa Lab studies the properties of materials made of molecules, such as organic semiconductors and molecular ferroelectrics, and how to use them in devices. Aiming at flexible electronics, the lab develops foundational technologies for turning organic semiconductors, organic conductors, and ferroelectrics into devices by printing. The lab aims to control the complex structures that form when molecules self-assemble, and to bring out both the properties unique to molecular materials and new device functions.

Toshiya Ideue, Associate Professor
Quantum & Condensed Matter1 student voices
The Ideue Lab studies the properties and functions of materials that are only a few atoms thick. Layered crystals can be turned into thin films simply by peeling them off with tape, and they show properties different from those of three-dimensional crystals. By stacking many kinds of atomic layers and applying electric fields, magnetic fields, or pressure, the lab controls the symmetry and quantum-mechanical degrees of freedom of materials. Combining electrical and optical measurements, the lab searches for new phenomena in electrical conduction, superconductivity, and optical properties.

Katsuyuki Fukutani, Professor
Quantum & Condensed Matter1 student voices
The Fukutani Lab is a surface science and vacuum science lab that studies phenomena occurring at solid surfaces and interfaces. Surfaces have lower dimensionality and symmetry than three-dimensional bulk, and show distinctive properties such as interface superconductivity, surface magnetism, and catalytic effects. Solid surfaces play an especially important role in the production, storage, and sensing of hydrogen, a clean energy carrier. Through work such as the development of spin-polarized hydrogen, the lab aims to uncover the mechanisms of spin conversion and molecule formation at surfaces.

Keiji Sakai, Professor
Materials & Nanotech1 student voices
The Sakai Lab develops its own technologies for measuring the physical properties of liquids and soft materials. The lab ejects droplets about the size of a cell into the air and captures them, then studies phenomena unique to the microscale. By observing collisions between droplets and the oscillation of droplets that hit a substrate, the lab also measures properties such as surface tension. The lab has also developed a new type of viscometer based on the electromagnetically spinning (EMS) method, and is advancing joint research with industry and medicine.

Shuntaro Takeda, Associate Professor
Quantum & Condensed Matter1 student voices
The Takeda Lab studies optical quantum computers and their applications. By exploiting properties unique to quanta of light, it is possible to realize quantum computers that operate at room temperature and in ambient air, with a high clock rate. The lab is advancing the development of optical quantum computers through its own original approach, and is also exploring practical applications that use this technology. Using quanta of light also opens up possibilities for communication and measurement that go beyond conventional technologies.

Masato Koashi, Professor
Quantum & Condensed Matter1 student voices
The Koashi Lab studies quantum information and quantum optics, fields where quantum theory and information science meet. By making good use of the strange behavior of physical systems governed by quantum mechanics, the lab opens paths toward highly secure optical communication and high-speed computation. Conversely, the lab also aims to re-examine quantum mechanics through the rigorous logic of information science and to approach the fundamental structure of the laws of nature.

Hidetoshi Katori, Professor
Quantum & Condensed Matter1 student voices
The Katori-Ushijima Lab explores the physics and engineering of spacetime using the "optical lattice clock," which was proposed in this lab. The optical lattice clock is an extremely precise atomic clock that is drawing attention as a leading candidate for the future redefinition of the second. By combining techniques for manipulating ultracold atoms and controlling lasers, the lab further improves the clock's precision and uses that precision to explore uncharted physics and applied technologies. The lab has bases at both the University of Tokyo and RIKEN, where members conceive and build experimental apparatus that exists nowhere else in the world.

Youtarou Takahashi, Associate Professor
Quantum & Condensed Matter1 student voices
The Takahashi Lab conducts research in condensed matter physics using light. The lab focuses on the unique properties of materials discovered in recent materials science, and performs state-of-the-art optical measurements from the terahertz range to the ultraviolet. It aims to pioneer new optical functions and to understand the dynamics, meaning the motions occurring inside materials. Lab visits are accepted at any time.

Michihisa Yamamoto, Professor
Quantum & Condensed Matter1 student voices
Yamamoto Lab conducts research on building quantum electronic devices based on techniques for controlling and transmitting quantum degrees of freedom in solids. Its experiments include controlling, one electron at a time, the quantum states of electrons traveling through semiconductor microstructures, and transmitting and controlling new quantum degrees of freedom in atomically thin materials. The lab elucidates how quantum coherence spreads and the physics of quantum correlations, in order to establish guiding principles for quantum devices. The lab also aims to use advanced quantum technology to solve problems in condensed matter science from a microscopic perspective.
