Seeking a Postdoctoral Researcher

Research field and overview

The Center for Emergent Matter Science (Center Director: Dr. Yoshinori Tokura) is a strategic research center launched on April 1st, 2013. The center aims at constructing a novel condensed matter science and contributing fundamentally toward the realization of an environmentally benign, sustainable society which is recognized as a world-wide problem

The Quantum Function System Research Group aims at developing novel concepts and electronics bases relevant for quantum control and quantum information technology with semiconductor nanostructures. The major research topics include physics and technology of quantum computation and quantum state control including quantum coherence, quantum spin correlation, and many-body effect. We have newly started an experimental research project on further advanced quantum information science including dynamics of open non-equilibrium quantum systems, spin-based quantum algorithms, and quantum feedback with quantum dot arrays. Applications of those who have experimental expertise about nano-electronics and quantum information technology are greatly encouraged.
