This summer cohort 3 from the QE CDT visited Hitachi Cambridge Laboratory part of Cavendish laboratory in Cambridge. Their visit was hosted by Dr Fernando Gonzalez-Zalba, who gave a talk presenting an overview of the approach Hitachi’s spintronics research group takes towards quantum computing. Students learned more about the progress made on adapting current CMOS technology to store electron spin qubits which takes advantage of the ease of access to high quality devices capable of showing quantum effects.

Student Brian Flynn shares his impression of the visit: ‘It was great to see what sort of challenges industrial efforts are addressing. We've seen how academia approaches quantum technology from a "proof-of-principle" perspective; Hitachi are thinking about millions of qubits. Thinking at this scale is important for the next ten years of quantum computing.’

The QE CDT students were also taken on a lab tour around the facilities on site where they observed low temperature CMOS integrated circuits. Experimentalists from the CDT were also impressed by the variety of advanced cooling equipment.

The excursion, part of the topics in Quantum Engineering module, was organised by student David Ibberson who, at the time, was carrying out an individual research project under Fernando’s supervision. He is optimistic about the future of the laboratory: ‘I think it sets a good example for collaboration between industry and academia. Demonstrates what's possible when both sides pool their resources and researchers under one roof.’ David has since extended his work on the project into his PhD on the topic of ‘Gate-based single-shot readout of electron-spin qubits in CMOS devices’ co-supervised by Dr Ruth Oulton in Bristol.
