Novel Architectures Based on Superconducting Quantum Circuits and Hybrid Quantum Systems

Master’s Project Description
Superconducting quantum computing is among the most advanced quantum platforms. Despite rapid progress driven by major academic and industrial efforts, it remains unclear how current technologies can be scaled up to achieve fault-tolerant quantum computing with millions of superconducting qubits.
The Superconducting Quantum Optics Lab, a newly established group led by Assistant Prof. Shingo Kono, seeks to address this challenge by exploring fundamental approaches that enable novel quantum protocols and systems, with the goal of achieving scalability and high fidelity in the next generation of quantum computing.
Our main research directions are:
- Investigating quantum decoherence mechanisms in superconducting quantum circuits
- Developing broadband, quantum-limited Josephson parametric amplifiers for scalable quantum computing
- Exploring hybrid quantum systems that integrate superconducting circuits with mechanical membranes and magnetic crystals, enabling long-lived quantum memories and nonreciprocal quantum devices, respectively
By joining the lab, you will gain hands-on experience in both the fundamentals and state-of-the-art technologies of superconducting quantum circuits, working on your own project in close collaboration with senior group members. The PI is committed to supporting the growth of students who aspire to bridge deep theoretical understanding with advanced experimental expertise.
Research Project Examples:
Specific projects are defined through discussions with the PI. Examples include:
- Designing quantum experiments to reliably and efficiently identify decoherence mechanisms in state-of-the-art superconducting circuits
- Designing and developing sample packages tailored for scalable quantum systems, Josephson parametric amplifiers, and hybrid systems, respectively
- Theoretical modeling, design, and measurement of novel Josephson parametric amplifiers
- Theoretical modeling, design, and measurement of novel 3D integrated superconducting circuits for hybrid quantum systems
- Developing nanofabrication processes for circuit optomechanical systems based on vacuum-gap capacitors
Expected Qualifications:
We are looking for motivated master’s students eager to take on the formidable challenges of realizing fault-tolerant quantum computing from fresh and innovative perspectives. We warmly welcome applicants with broad interests in quantum science, especially those with backgrounds in physics, nanoscience, or related fields.
