Curriculum Vitae

Danyang Chen

I’m a graduate student at Northwestern University, specializing in device theories for superconducting qubits. My research spans from the optimal realization of the physical qubits to its application to quantum information.

While I’m primarily dedicated to this area, I maintain a broad interest including open quantum systems and quantum information science.

On-going projects

  • Scaling Up Fluxonium-Based Quantum Processors: Challenges and Potential Solutions
    Design and simulate multi-fluxonium quantum systems and verify their performance with experimental colleagues
  • Error Budgeting for a Quantum Error Correction Protocols
    From the device level, perform error budgeting analysis for quantum error correction (QEC) protocols. With a figure of merit that can be quickly calculated, we optimize the device parameters and improve the QEC performance.
