María Gragera Garcés

I'm a PhD student at The University of Edinburgh's School of Informatics, where I research distributed quantum computing. I am co-supervised by Chris Heunen and Mahesh Marina, partially funded by the Oxford Quantum Technology Hub DTP and VeriQloud, and working within the Quantum Software Lab.

Previously, I completed a BSc with Honours in Physics at the University of Bath and worked in various roles in the quantum industry within companies such as Cisco and IBM.
