Research Field

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.

Our team is involved in Quantum Leap Flagship Program in which we develop superconducting quantum circuits for quantum information processing. Through larger-scale integration of qubits, higher-fidelity control and readout, and longer coherence of qubits, we aim at the realization of a quantum computer. Therefore, we are hiring a postdoctoral researcher or a research scientist who has experience and expertise in experimental research on quantum electronics, quantum information scientist, condensed matter physics, etc.
