HELLO, MY NAME IS

I-LI CHIU

Physics M.S. Student · Superconducting Circuits

I am a physics M.S. student at National Central University working on superconducting circuits. I study how physical models become trustworthy numerical results and build research tools that make models, simulation workflows, and results inspectable.

Core Expertise

Computational Electromagnetics & FEM

Derive weak formulations, basis functions, and matrix discretizations from electromagnetic and electrostatic governing equations; examine how materials, boundary conditions, meshes, and convergence affect fields and derived quantities.

RF/Microwave Network Analysis

Use multiport S-, Y-, and Z-parameters and their conversions; account for port definitions, reference impedances, and terminations when interpreting reflection and transmission.

Superconducting Circuit Modeling

Connect nodal admittance, modes, and poles to circuit coupling and energy-relaxation questions.

About Me

I work from physical assumptions through circuit and electromagnetic models to results that can be inspected and compared. Research workflows matter to me because they keep those steps connected.

I collaborate with AI agents to explore approaches, draft implementations, and organize documentation. I then use physical reasoning, numerical checks, and comparisons with published and other existing work to examine the assumptions, methods, and results.

Research

Floating-Qubit Energy Relaxation Study

Undergraduate thesis, National Central University

  • Model validation
  • Admittance formulation
  • Full-wave FEM
  • Framed the physical model: Applied an admittance-based formulation to describe floating-qubit coupling paths and make the energy-relaxation mechanism explicit enough for analytical and numerical review.
  • Cross-checked assumptions: Compared quasi-static extraction with full-wave finite-element simulation to identify where model assumptions stayed consistent and where numerical differences could arise.

Layout-to-FEM Research Workflow

Research data generation through simulation automation

  • Physical modeling
  • Simulation automation
  • Parameter sweep
  • Built an iteration loop: Developed a data-generation workflow from GDSII layout to FEM simulation, connected to parametric design tooling so layout changes could become solver-ready experiments more quickly.
  • Mapped circuit parameters: Linked lumped circuit models to Hamiltonian-level quantities around coupling strength and ZZ interaction space, enabling targeted scans for calibration-sensitive parameters.

Additional Practice

  • Used National Center for High-performance Computing (NCHC) resources and mesh-refinement studies to compare solver cost, numerical differences, and reliability.
  • Helped maintain a lab Synology NAS and maintained a personal TrueNAS/Docker environment for research data, backups, and local compute.
