Biography

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.

 

Research interests

My research broadly concentrated on the development of novel software and hardware architecture (based on hybrid semiconducting, graphene, and superconducting quantum materials) for robust quantum computing, quantum information, quantum communication, and green energy.

I lead a team of researchers undertaking multidisciplinary research at the forefront of micro, nano, and quantum science and technology. This includes the design, modeling, fabrication, characterization, and measurements of nanoelectronics and nanophotonic quantum devices such as:

-(Hybrid) Superconducting resonators, coherent quantum integrated circuits and qubits,

-(Josephson junction-based) chip-integrated microwave, and THz coherent light sources, THz science & technology,

-Micro and nano-engineered quantum devices such as antenna arrays, metamaterials, and waveguides for ultrafast quantum photonics.
