Andrew Hutcheson

Andrew Hutcheson is a scientist in the Quantum Computing Circuits group within the Quantum Technologies department at NPL and a PhD student in the Department of Materials at Imperial College London.

His research focuses on understanding the material properties of quantum devices and how they relate to performance limitations, helping to support the growth of quantum computing technologies.

Key characterisation techniques used in his research include Scanning Probe Microscopy (SPM), which is used to investigate individual atomic-scale electronic defects, and Electron Spin Resonance (ESR), which is used to detect paramagnetic defects in superconducting quantum circuit components, such as qubits and resonators.

Research interests

• Two-level system (TLS) defects arising from the amorphous nature of superconducting materials.
• Paramagnetic centres and their contribution to noise in quantum devices.
• Identifying other sources of noise in quantum computing devices and developing approaches to reduce their impact.
