WSH: Microwave Quantum Engineering: From Methods to Hardware and Algorithms

Presentation Abstract
The rapid progress in quantum computing has made microwave engineering a key enabler of nearly all major hardware platforms, including superconducting qubits, spin qubits, trapped ions, etc. Each of these technologies relies on advanced microwave techniques for control, coupling, readout, and scaling, demanding approaches that go well beyond classical electromagnetics. This creates a great opportunity for microwave engineers to make lasting contributions to the development of quantum computing and related technologies. The need for ultra-low-noise amplification, high-fidelity readout, and crosstalk suppression has stimulated novel device designs, often requiring hybrid approaches that combine electromagnetic modeling with quantum theory. Similar challenges appear in other quantum platforms; for example, trapped-ion processors demand stable and phase-coherent microwave delivery for multi-qubit gates, while spin qubits rely on advanced microwave control schemes. At the algorithmic level, quantum computing is increasingly viewed as a potential game-changer for electromagnetics and related fields. Specialized quantum algorithms promise significant acceleration for tasks such as solving integral equations, optimizing antenna radiation patterns, or addressing NP-hard problems in inverse scattering and system design. While fully fault-tolerant quantum computing remains a long-term goal, near-term noisy intermediate-scale quantum devices are already serving as valuable testbeds. Hardware-aware algorithm design, ie tailoring quantum algorithms to the specific strengths and limitations of physical devices, is becoming an essential strategy for identifying useful applications in the presence of noise and limited coherence times. This workshop will highlight state-of-the-art advances at the interface of microwave engineering, quantum hardware development, and quantum algorithm design. Contributions will cover multiple quantum platforms, emphasizing both their unique microwave engineering challenges and the unifying principles that connect them. A particular focus will be placed on industrial perspectives, including scalability, reliability, and manufacturability of microwave components for large-scale quantum systems. Industry engagement is crucial, as commercial interest and investment in quantum computing have surged dramatically, creating demand for engineers who can translate fundamental concepts into deployable technologies. To ensure accessibility, the workshop will open with a comprehensive tutorial introducing the basics of quantum theory in the language of microwave engineering. This will help participants from the RF and microwave community engage with the specialized concepts of quantum physics and better appreciate their role in quantum device design. The program will then feature a series of invited talks from leading experts in academia and industry, with topics spanning theoretical methods, quantum hardware, and algorithmic perspectives. By bringing together specialists from diverse quantum hardware platforms, algorithm developers, and industrial leaders, this workshop will provide a unique forum for exchanging ideas, identifying cross-platform synergies, and further drafting the engineering roadmap toward practical, scalable quantum computing.
