Seeking a Postdoctoral Researcher(W638)

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 and quantum spin correlation. We have newly started an experimental research project on advanced quantum technologies based on Si quantum dots, including development of scalable spin qubits and circuits and spin-based quantum algorithms. Applications of those who have experimental expertise about Si devices and circuits and quantum transport are greatly encouraged.
