Symposium B

Erika Kawakami received her Ph.D. from Delft University of Technology in the Netherlands and was a postdoctoral researcher at the Okinawa Institute of Science and Technology (OIST) in Japan before starting her research group at RIKEN. Her research focuses on quantum information processing using electrons on helium and solid neon.

Kenta Takeda is a Senior Scientist at RIKEN. He received his Doctor of Engineering in Applied Physics from the University of Tokyo. His research focuses on semiconductor quantum dots and their applications in quantum information processing. His key publications include pioneering work on high-fidelity single- and two-qubit gates, as well as the demonstration of three-qubit quantum error correction using silicon-based quantum-dot spin qubits. He is currently focused on developing multi-qubit control techniques and scalable quantum computing architectures for semiconductor-based quantum systems.

Sadashige Matsuo is an Associate Professor at Institute of Science Tokyo. He received his Ph.D. in Science from Kyoto University. His research explores quantum transport in nanoscale solid-state devices, with a particular focus on hybrid systems combining semiconductors and superconductors. By designing electrically tunable Josephson junctions and related nanostructures, he investigates how superconducting coherence gives rise to emergent quantum states such as Andreev molecules. His recent work aims to establish new ways to engineer and control superconducting transport, Josephson diode effect, and topological superconducting states, providing a foundation for future Majorana-based quantum devices and scalable superconducting quantum technologies.
