WME: Microwave Design for Superconducting Qubits and Quantum Amplifiers: From Fundamentals to Scalable Architectures

Presentation Abstract
Superconducting qubits have emerged as a leading platform for scalable quantum computing, offering robustness, manufacturability, and seamless integration with microwave engineering techniques. This workshop presents a comprehensive journey from the foundational principles of superconducting quantum systems to advanced microwave design strategies that enable scalable architectures. We begin by exploring the physics of Josephson junctions — the non-linear inductive elements that form artificial atoms — and their integration into quantum circuits. Participants will gain insights into the design and simulation of qubit-resonator networks, quantum amplifiers, and cryogenic microwave systems operating within dilution refrigerators at millikelvin temperatures. Key engineering challenges will be addressed, including resonance frequency tuning, qubit-resonator coupling, and quantum parameter optimization (eg anharmonicities, cross-Kerr effects). The workshop will also examine the role of quantum amplifiers in enhancing readout fidelity and the importance of scalable microwave layouts for multi-qubit systems. Using real-world examples and simulation workflows, we will demonstrate how to accelerate development cycles and improve design accuracy. Attendees will leave with a clear understanding of how microwave engineering principles intersect with quantum hardware design, paving the way for scalable quantum computing architecture.
