- Additional information
- The work has demonstrated that superconducting quantum bits are subject to long-term drifts in qubit lifetime, phase stability and frequency caused by single microscopic defect states near their tunnel junction. It underpinned the EPSRC Award (EP/T018984/1, https://gow.epsrc.ukri.org/NGBOViewGrant.aspx?GrantRef=EP/T018984/1, £515k) and led to an Innovate UK Grant (ISCF CR&D 50868) on creating reliable, high throughput production and characterisation of coherent superconducting devices with Oxford Instruments Ltd.
