Machine Learning for Semiconductor Quantum Devices

Overview

Quantum computing is a fast-growing technology and semiconductor chips are one of the most promising platforms for quantum devices.
The current bottleneck for scaling is the ability to control semiconductor computing chips quickly and efficiently.

This course, aimed at students with experience equivalent to a master’s degree in physics, computer science or electrical engineering introduces hands-on machine learning examples for the application of machine learning in the field of semiconductor quantum devices. Examples include coarse tuning into the correct quantum dot regime, specific charge state tuning, fine tuning and unsupervised quantum dot data analysis.

After the completion of the course students will be able to

assess the suitability of machine learning for specific qubit tuning or control task and
implement a machine learning prototype that is ready to be embedded into their experimental or theoretical quantum research and engineering workflow.
