Dr. Michal Bajcsy is an Associate Professor in the Department of Electrical and Computer Engineering and has an affiliation with the Institute for Quantum Computing at the University of Waterloo.

He earned his PhD in Applied Physics and a Bachelor of Science in Electrical and Computer Engineering from Harvard University’s School of Engineering and Applied Sciences.

Dr. Bajcsy’s groundbreaking doctoral research, supervised by Mikhail Lukin, included the demonstration of stationary light pulses and studies of interactions between tightly confined cold atoms and few-photon pulses within hollow-core photonic-crystal fibers. He further enriched his research experience as a visiting student in Vladan Vuletić's group at MIT. Following his PhD, he completed postdoctoral training at Stanford University in the Nanoscale and Quantum Photonics Lab under Jelena Vučković, focusing on solid-state cavity QED systems using quantum dots embedded in photonic crystals.

At the University of Waterloo, Dr. Bajcsy’s research centers on developing scalable photonic devices and quantum optics experimental platforms. His work leverages quantum emitters such as laser-cooled atoms, quantum dots, and color centers, integrated with nanophotonic structures, to advance the frontier of quantum technologies.
 

Dr. Na Young Kim is an Associate Professor in the Department of Electrical and Computer Engineering at the University of Waterloo. She is affiliated with the Institute for Quantum Computing (IQC) and the Waterloo Institute for Nanotechnology (WIN) and holds cross-appointments in the Departments of Physics and Astronomy, and Chemistry.

As the leader of the Quantum Innovation (QuIN) Laboratory, Dr. Kim drives cutting-edge research to develop large-scale quantum processors using novel materials and advanced technologies. Her team is currently spearheading two major projects:

1. Semiconductor Quantum Processors – This project explores controllable optical and electrical domains, unveiling the properties of exotic materials and the fundamental nature of symmetries.
2. Multi-Functional Classical and Quantum Device Arrays – This initiative aims to establish a planar architecture integrating nano-scale devices with electrical, optical, thermal, and mechanical functionalities.

Before joining the University of Waterloo in 2016, Dr. Kim worked at Apple Inc., where she contributed to the development of small display products. She earned her BS in Physics from Seoul National University and completed her graduate studies at Stanford University’s Department of Applied Physics, focusing on mesoscopic transport properties in low-dimensional nanostructures. Her postgraduate research expanded into quantum optics and nanophotonics, encompassing both experimental and theoretical projects in collaboration with leading scholars.

Dr. Amir Hamed Majedi is a Professor in the Department of Electrical and Computer Engineering at the University of Waterloo, with a cross-appointment to the Department of Physics and Astronomy. He leads the Integrated Quantum Optoelectronics Lab (IQOL) within the Waterloo Institute for Nanotechnology.

Dr. Majedi’s research focuses on engineering quantum electrodynamics, with an emphasis on superconducting optoelectronics and quantum photonics. His key research areas include:

• Superconducting nanowire single-photon detectors
• Single-photon sources based on nanowire quantum dots
• Superconducting plasmonic detectors and waveguides
• Superconducting-based quantum dot LEDs for single and entangled photon sources
• Graphene photonics

The IQOL conducts theoretical and experimental investigations into quantum and electromagnetic phenomena in superconducting micro- and nanoscale structures. The lab aims to advance technologies in optoelectronic, millimeter-wave/THz, and photonic devices and systems. Their research seeks to establish theoretical foundations, innovative design methodologies, and device/system-level synthesis and characterization techniques.

Through this work, the lab is driving the development of superconducting quantum devices for cutting-edge applications, including ultrafast communications, quantum information processing, and bio-nanotechnology.

Dr. Guo-Xing Miao is an Associate Professor in the Department of Electrical and Computer Engineering at the University of Waterloo, with an affiliation to the Institute for Quantum Computing (IQC).

Dr. Miao’s research focuses on spintronics, utilizing precise electron spin manipulation to enable information processing. His work emphasizes nanodevices established on newly emerging spin platforms, such as synthetic diamonds and topological insulators, where information can be processed coherently on the quantum level, rather than digitally on the classical level. The interwined transport of electrons, spins and ions in solid-state devices establishes the forefront for developing semiconductor compatible materials platforms ready for chip integration.

Dr. En-Hui Yang is a Professor in the Department of Electrical and Computer Engineering at the University of Waterloo and the founding Director of the Leitch-University of Waterloo Multimedia Communications Lab. He is also the co-founder of SlipStream Data Inc. (now a subsidiary of BlackBerry Inc., formerly known as Research In Motion) and a former associate editor for IEEE Transactions on Information Theory. He previously held a Tier 1 Canada Research Chair in Information Theory and Multimedia Data Compression.

Dr. Yang is known for co-developing the Yang-Kieffer algorithm, a numerical set of rules that use grammar-based coding to achieve lossless compression of text and image files. He is also the co-inventor of soft decision quantization (rate distortion optimization quantization or trellis quantization), an efficient coding technology used in image and video applications to improve compression, with widespread use in products like smartphones and web browsers.

His research interests span multimedia compression, information theory, digital communications, image and video coding, image understanding and management, big data analytics, information security, and deep learning. His work aims to develop technologies that enhance storage capacity of computers, accelerate and improve reliability of data transmission, improve data security, and make big data more understandable.

Dr. Yang is a Fellow of the Canadian Academy of Engineering, a Fellow of the IEEE, and a Fellow of the Royal Society of Canada. In 2024, he was honored with the title of 'University Professor' by the University of Waterloo in recognition of his exceptional scholarly achievements and international pre-eminence.

Sujeet K. Chaudhuri is a distinguished professor emeritus in the Department of Electrical and Computer Engineering (ECE) at the University of Waterloo. In recognition of his sustained outstanding scholarship and academic leadership, Professor Chaudhuri was installed in 2004 as the O’Donovan Research Chair of RF/Microwaves and Photonics at the university. He was the Chair of the Department of Electrical and Computer Engineering from 1993 - 1998 and the Dean of the Faculty of Engineering from 1998-2003.

Under Professor Chaudhuri’s leadership, initially as the Chair, and later as the Dean, the university experienced unprecedented growth. The research budget of the faculty tripled, new buildings were added, and new undergraduate programs like Software Engineering and Mechatronics Engineering were successfully introduced. Several graduate/research programs were also new additions to the university. As the Chair of the National Council of Deans of Engineering and Applied Sciences (NCDEAS), Professor Chaudhuri provided new visions and progressive leadership to the Engineering Profession in Canada. Due to his initiatives, NCDEAS now enjoys a prominent consultative role with governments and the private sector in North America.

Current research interests of Professor Chaudhuri include guided-wave/electro-optic structures, planar microwave structures, dielectric resonators, optical and EM imaging, fiber based broadband network and the emerging technologies based on the EBG/PBG-nanostructures. Additionally, Professor Chaudhuri is a member of URSI Commission B, and Sigma Xi.
