Jan Kycia
IQC Associate, Professor, Department of Physics & Astronomy
Jan Kycia's research group, the Kycia Low Temperature Group, works on the experimental investigation of quantum mechanical properties of sub-micron and micron scaled superconducting devices. In particular superconducting single electron transistors (sSETs) and superconducting quantum interference devices (SQUIDs). They are focusing on gaining a better understanding of how dissipation and the environment affect the states of the devices. They also study the 1/f noise in Josephson junctions. This 1/f noise may be an intrinsic limitation to the coherence time of superconductor-based qubits.
Anthony Leggett
Professor, University of Illinois at Urbana-Champaign
Anthony J. Leggett, the John D. and Catherine T. MacArthur Professor and Center for Advanced Study Professor of Physics, has been a faculty member at Illinois since 1983. He is widely recognized as a world leader in the theory of low-temperature physics, and his pioneering work on superfluidity was recognized by the 2003 Nobel Prize in Physics. He is a member of the National Academy of Sciences, the American Philosophical Society, the American Academy of Arts and Sciences, the Russian Academy of Sciences (foreign member), and is a Fellow of the Royal Society (U.K.), the American Physical Society, and the American Institute of Physics. He is an Honorary Fellow of the Institute of Physics (U.K.). He was knighted (KBE) by Queen Elizabeth II in 2004 "for services to physics." He is also a Mike and Ophelia Lazaridis Distinguished Research Chair.
Professor Leggett has shaped the theoretical understanding of normal and superfluid helium liquids and other strongly coupled superfluids. He set directions for research in the quantum physics of macroscopic dissipative systems and use of condensed systems to test the foundations of quantum mechanics. His research interests lie mainly within the fields of theoretical condensed matter physics and the foundations of quantum mechanics. He has been particularly interested in the possibility of using special condensed-matter systems, such as Josephson devices, to test the validity of the extrapolation of the quantum formalism to the macroscopic level; this interest has led to a considerable amount of technical work on the application of quantum mechanics to collective variables and in particular on ways of incorporating dissipation into the calculations. He is also interested in the theory of superfluid liquid 3He, especially under extreme nonequilibrium conditions, in high-temperature superconductivity, and in the newly realized system of Bose-condensed atomic gases.
Research Interests:
- Theoretical Condensed Matter of Physics
- Low Temperature Phenomena
- Quantum Fluids
- Statistical Physics
- Macroscopic Quantum Systems
- Quantum Theory of Measurement

James Martin
IQC Associate Professor Department of Physics
James obtained his PhD from the University of Waterloo in 1998 under the supervision of J. W. Hepburn (now at UBC). His thesis was titled: "Electric-Field Induced Dissociation of Molecules in Rydberg-Like Highly Vibrationally Excited Ion-Pair States". This work explored the analogy between the motion of two bound oppositely charged atomic ions moving within an excited molecule (an ion-pair state) and a highly excited electron circling an atomic ion (a Rydberg state). In particular, in this work it was proposed and demonstrated (for the first time) that ion-pair states could be dissociated using very weak electric fields. After completing his thesis, James moved to Long Island, New York to work at Brookhaven National Laboratory for L. F. DiMauro on the generation of intense short pulse infrared using high intensity lasers. While there he studied high-harmonic generation using short-pulse mid-infrared. In August 1999 he moved to the University of Virginia in Charlottesville, Virginia to study Rydberg atoms in T. F. Gallagher's group. While there he worked on the stabilization of predissociating molecular Rydberg states using microwave and radio-frequency fields and the dipole-dipole interaction between cold Rydberg atoms (obtained from excitation of laser cooled atoms). In the Fall of 2000 he returned to the University of Waterloo to set up a laboratory to study basic atomic, molecular and optical physics. At the present time, his group is constructing a laser cooling and trapping apparatus suitable for investigating a wide variety of phenomena associated with cold Rydberg atoms.
Research Interests: Rydberg states, laser cooling of atoms and molecules, dipole-dipole interaction between Rydberg atoms and its applications in quantum information processing.
Eduardo Martin-Martinez
Department of Applied Math, Professor | IQC Associate
There is strongly increasing interest in understanding entanglement and quantum communication in curved spacetimes, and in using quantum information techniques to address questions in gravity and quantum field theory. The new and very active field of relativistic quantum information was recently born to address these questions and it is set to continue developing at this fast pace during the next decade due to continued input from Earth-bound and from projected satellite-based experiments on spacetime curvature, gravitational waves and relativistic aspects of quantum entanglement.
Eduardo’s research combine the fields of quantum information science, quantum field theory and general relativity; studying quantum effects induced by gravity from the perspective of quantum information to gain information about the spacetime structure. This approach has a wide range of potential outcomes and applications from quantum computing technology to the basic physics of the question of how the spacetime curvature and quantum theory impact the flow and the processing of information.
Eduardo completed his PhD in Theoretical Physics in 2011 at the UCM (Universidad Complutense de Madrid, Spain) with “summa cum laude” and receiving the "2010-2011 extraordinary PhD thesis award". During his PhD period he collaborated with top scientists in relativistic quantum information in Canada, United Kingdom, Austria, Japan and Poland. In 2012 he moved to the Institute for Quantum Computing at the University of Waterloo for his first postdoctoral appointment. In October 2012 he was awarded the prestigious Banting Postdoctoral Fellowship. He was also an associate postdoctoral researcher at Perimeter institute.
In 2014 Eduardo was named a Research Assistant Professor at the Institute for Quantum Computing, cross-appointed to the Perimeter Institute. Soon afterward, he was awarded the prestigious John Charles Polanyi Prize for Physics.
In July 2016 Eduardo was appointed Assistant Professor in the department of Applied Mathematics at the University of Waterloo, becoming an IQC Associate and a Perimeter Institute Affiliate. In July 2020 Eduardo was granted tenure and promoted to Associate Professor and in July 2024 he was promoted to Full Professor.

Joel Wallman
IQC Associate
Joel Wallman obtained his BSc (Advanced) in Physics and Mathematics at The University of Sydney (Australia) in 2008 with Honours and was awarded the University Medal for outstanding academic achievement. Wallman completed his PhD in Physics from The University of Sydney (USYD) in 2013 with his thesis titled: Information, Observers, and Quantum Mechanics. He was awarded the Vice-Chancellor’s Research Scholarship (USYD) and the Denison Merit award (USYD) for his outstanding track record of academic achievement and research potential.
Wallman completed a postdoctoral research position in 2013 at USYD before moving to the Institute for Quantum Computing (IQC) at the University of Waterloo to pursue a postdoctoral position under Joseph Emerson. In 2016 he was awarded a Foundational Questions Institute (FQXi) Physics of the Observer grant.
After spending two years as Research Assistant Professor, Wallman was named Assistant Professor at IQC and in the Department of Applied Mathematics at the University of Waterloo in 2019. During his time at Waterloo he held the position of CTO at Quantum Benchmark, the start-up company he co-founded with Emerson. In 2021, Quantum Benchmark was acquired by Keysight Technologies, where Wallman is now the Research & Development Operations Manager.
