Two-Qubit Transmon System

Problem

The objective of this project was to design a two-qubit transmon system and explore layout-level considerations for superconducting quantum circuits. The focus was on understanding geometry, coupling, and practical design constraints rather than full device fabrication.

Approach

I designed the system using Qiskit Metal, iterating on qubit geometry and placement to achieve controlled coupling and a clean, analyzable layout. The design process was guided by literature and hardware-aware intuition rather than purely abstract models.

Tools

• Qiskit Metal
• Scientific literature on superconducting qubits
• Layout-based reasoning and visual inspection

Results

A functional two-transmon layout was successfully created, providing a compact platform for studying qubit–qubit coupling, symmetry, and future readout-oriented design considerations.

What I Learned

This work improved my intuition for quantum hardware design and emphasized the importance of layout-level thinking in superconducting circuits. It also strengthened my ability to translate theoretical concepts into physically meaningful structures.
