Earlier this year, Nottingham-based Cerca Magnetics won the inaugural IOP qBIG Prize for quantum innovation for the development of its OPM-MEG wearable brain scanner. The prize is awarded by the Institute of Physics and is sponsored by the UK-based investment firm Quantum Exponential.

In this episode of the Physics World Weekly podcast my guests are David Woolger, who is CEO of Cerca Magnetics and Stuart Nicol, who is chief investment officer at Quantum Exponential. We talk about the quantum technology behind Cerca’s brain scanner and explore the relationship between quantum start-up companies and the firms that provide them with the funds needed to develop their products.
