This episode of the Physics World Weekly podcast features an interview with the physicist Maria Schuld, who is a senior researcher and software developer at Xanadu – a Toronto-based quantum technology company. She talks about the challenges and rewards of implementing machine-learning systems on quantum computers.

Also on hand is the author Kit Chapman, who chats about his latest book Racing Green: How Motorsport Science Can Change the World. He explains how the myriad technologies developed to make racing cars faster and safer have already benefitted society – and how they could help us combat climate change.

• You can read Maria Schuld’s latest work on quantum machine learning on the arXiv preprint server.
