Research interests: superconducting optoelectronics; microwave-photonics/quantum devices; electromagnetic band gap structures
Professor A. Hamed Majedi leads the Integrated Quantum Optoelectronics Lab (IQOL) for characterization of superconducting and photonic quantum devices, especially superconducting single-photon detector.
Majedi is investigating theoretical and experimental techniques to characterize quantum optoelectronic and microwave-to-terahertz photonic devices, especially based on superconducting materials. This new knowledge will become the building blocks for new photonics-based technologies in quantum information processing, nano-photonics, on-chip quantum optoelectronics and bio-nano systems.
Majedi was born in Tehran, Iran and did his BSc in Electrical Engineering at K. N. Toosi University of Technology, Tehran, Iran. He received his MSc in Electrical from AmirKabir University of Technology with honours. In 1998, he joined the Electrical & Computer Engineering Department, at the University of Waterloo and obtained his PhD with distinction on December 2001. His PhD thesis investigated the optical-microwave interaction in superconducting transmission lines for optoelectronic applications. After Majedi completed his PhD, he spent 10 months as a postdoctoral fellow in the ECE department focusing on superconducting single photon detectors and THz photonic devices. Majedi is now an Associate Professor in the Electrical & Computer Engineering department, cross-appointed with the Institute for Quantum Computing (IQC) and Department of Physics and Astronomy.

Professor Majedi’s group, Integrated Quantum Optoelectronics Lab (IQOL), pursues theoretical and experimental investigations of quantum and electromagnetic phenomena in superconducting micro-to-nano scale structures to advance optoelectronic, mm-wave/THz and photonic devices and systems. A major objective of the group is to develop theoretical foundations, design methodologies, device/system level synthesis, and characterization techniques to make superconductive quantum devices for applications ranging from ultrafast communications and quantum information processing to bio-nanotechnology.
Work on single photon detection
Majedi is part of a multidisciplinary, multi-university team that’s working on quantum cryptography. The team’s goal is to engineer optoelectronic nanostructures that emit specialized photon pairs in which the photons are entangled: tied together so that influences to one photon can be immediately detected by its partner, even on the opposite side of the world. Majedi’s role is to develop a single photon detector to test entangled photon sources.
