Research Statement

Prof. Kou's work is at the interface of quantum information and condensed matter physics. Her lab focuses on building novel superconducting circuit elements and qubits as well as using superconducting circuits to probe condensed matter systems such as topological materials that may be useful for quantum information.

Post-Doctoral Research Opportunities

We are looking for postdocs to work on superconducting qubits and/or sensing of topological materials.

Graduate Research Opportunities

We are looking for students to work on building protected qubits using superconducting circuits.

Research Interests

• Topological materials
• Novel superconducting circuits
• Hybrid superconducting circuits
