About the Principal Investigator:

Kaveh Delfanazari is Assistant Professor (University Lecturer) of Electronic and Nanoscale Engineering, at the James Watt School of Engineering, University of Glasgow, UK, Senior Research Scientist at the University of Cambridge, UK, Researcher Co-Investigator of the EPSRC programme on 'Multiplexed Quantum Integrated Circuits (MQIC)', Senior Member of IEEE, member of the 'Scottish Centre for Innovation in Quantum Computing and Simulation (SCIQCS)', and A/Fellow of the Higher Education Academy, UK. 

Kaveh has held positions as Research Associate in quantum devices and circuits at the University of Cambridge, UK, Research Fellow, and Project Leader in superconducting and quantum metamaterials, at the University of Southampton, UK. Kaveh investigated integrated superconducting terahertz (THz) emitters and antennas- based on the Josephson effect- during his PhD work at the University of Tsukuba, Japan. His research works in Japan led him to receive Dean’s Award for Excellence in the PhD thesis, the Japanese government scholarship, several travel grants, and international best paper and presentation awards.

Dr. Delfanazari's research interests lie in the area of:

• Hybrid and Topological Quantum Processing/Computing, 
• Quantum Nanoelectronics and Josephson Junctions, 
• Photonic Metamaterials and Plasmonics, 
• Terahertz Science and Technology,
• On-chip Quantum Communication.

Dr. Delfanazari's research group aims at developing on-chip quantum light sources, RF/microwave/mm-waves/THz electronic/photonic integrated circuits, and robust quantum chips based on (hybrid) novel quantum materials for applications in secure communication systems and decoherence-free (topological) quantum processing and computing.
