Classify CS Diagrams with Neural Networks

In this video, we show how to view charge stability diagram classification as a routine machine-learning image processing task. We show how to classify charge stability diagrams using dense and convolutional neural networks. We also discuss the broader usage of these techniques in contemporary semiconductor qubit experiments.

Main takeaways

  •  
  • Distinguishing single and double quantum dot charge stability diagram maps straightforwardly on the known image classification problem
  • Classification can be achieved with the fully connected neural network, but convolutional neural networks are a better tool in this case since we are parsing the charge stability diagrams for a specific feature.

Further thinking

True or False: Charge diagram machine learning classification has been experimentally tested in multiple labs around the world.
