Automated gated quantum-dot 3D model generation and tuning for technology-computer aided design of realistic spin-qubit systems

Spin qubits—nanoscale quantum bits made in semiconductor materials—are a promising technology for building future quantum computers. They are highly miniaturized, can work at relatively higher temperatures than competing technologies, and can be made using standard industrial semiconductor-chip fabrication techniques, which makes them ideal for scaling up. However, traditional chip design software is not adequate for these devices because they operate under extremely low-temperature conditions and follow quantum physics rules.

To solve this, Nanoacademic created QTCAD®, the first commercial software designed to simulate spin qubits. QTCAD® is already used by researchers and engineers around the world. As devices get more complex, users need more automation to save time. This internship project will develop tools that automatically create 3D models of devices from simpler 2D designs and tune settings to get the desired performance—tasks that currently take a lot of manual work.

The intern’s work will become part of QTCAD®, helping users work more efficiently and supporting Nanoacademic’s efforts to provide tools and training for both academic and industry partners. These improvements will not only benefit users but also support Nanoacademic’s services, such as contract research and training in quantum technology programs worldwide.
