Dr Giorgos Georgiou

  • Lecturer in Microarchitectures for Quantum Engineering (Electronic & Nanoscale Engineering)

Biography

Dr. Georgiou is an Assistant Professor (Lecturer) at the department of Electronic and Nanoscale Engineering in University of Glasgow, since 2021. He is an expert in Quantum Nanoelectronics, ultrafast optics, opto-electronics, THz technology, photonics and metamaterials.

Dr. Georgiou leads the lab for Ultrafast Quantum Terahertz Nanoelectronics (ultraQUTE), and his research focusses on semiconductor Quantum Technologies (semiconductor qubits) and fundamental electron interactions in condensed matter systems. In addition, his research involves the development of novel electronic instruments for quantum technologies, and scaling up these technologies through opto-electronic approaches.

He studied ultrafast optics, THz optoelectronics and photonics at the Institute for Atomic and Molecular Physics (AMOLF), and the Technical University of Eindhoven (TU/e) in the Netherlands, from 2012-2016. Then he moved to Institute Neel, CNRS, France, where he worked on Quantum Nanoelectronics and cryo-optoelectronics from 2016-2021. There he developed ultrafast cryo-optoelectronic techniques that enable the study of ultrafast quantum dynamics in solid-state systems and he worked on the generation and detection of ultrafast flying qubits in semiconducting systems. 

He is the author of several peer-reviewed publications with 3 of them publised in Nature-family journals and he holds 3 patents on THz optoelectronic devices. He was recently awarded a New Investigator Award grant from the EPSRC to develop energy-efficient THz devices that can be integrated in cryogenic environments. 

Research interests

I am an experimentalist in ultrafast quantum nanoelectronics. My interests extend from novel quantum technologies and quantum nano-electronics to nano-photonics, plasmonics and THz opto-electronics. 

My research interests extend over a broad range. I studied for my MSc and PhD in the fields of ultrafast optics, nano-photonics and plasmonics and focussed on THz plasmonics and metamaterial devices. 

After finishing my PhD, I was very interested on novel quantum technologies and I radically changed my research field to Quantum nano-Electronics. I did research on innovative single electron sources, that can produce single electron wave-packets that are well-defined in the time domain. These wave-packets can be used to access in real-time ultrafast quantum mechanics, and observe timelapses of how electrons interact with their environment. 

My research at the UoG is on creating Ultrafast electron wave-packets with 1 ps time duration (or THz bandwidth), that can be used for THz Qubits. This will be achhieved by inter-disciplinary reseach in quantum nano-electronics, nano-photonics, plasmonics and THz opto-electronics.

In addition to that, my aim is to create electronic embedded systems that can assist quantum technologies, especially for automatic data acquisition and analysis, as well as their integration at extreme cryogenic environments.

My long term vision is to create the first THz qubits that can be used in future quantum technologies.
