Current graduate students

In an exhilarating convergence of education and quantum information, Quantum for Educators unfolded its 9th annual class from December 1 to 3, 2023. Hosted by the Institute for Quantum Computing (IQC) at the University of Waterloo, this professional development workshop left an indelible mark on secondary school science teachers passionate about bringing the marvels of quantum information science and technology into their classrooms.

Testing quantum satisfiability

CS/MATH Seminar - Dominic Verdon (University of Bristol)

University of Waterloo, 200 University Ave West, Waterloo ON QNC 1501 + ZOOM

The quantum Boolean satisfiability problem, quantum k-SAT for short, is the quantum analogue of the classical Boolean satisfiability problem. It is QMA_1-complete for k >2, and therefore appears very difficult to solve in general. In this talk I will discuss a property testing approach to quantum k-SAT which, given the promise that an instance of the problem is either (i) satisfiable or (ii) far from satisfiable by a product state, yields a polynomial-time algorithm for deciding which of the two mutually exclusive properties (i) or (ii) holds. To show this we apply some tools from combinatorics, entanglement theory and algebraic geometry. The talk is based on joint work with Ashley Montanaro and Changpeng Shao (

Sometimes, new scientific discoveries can be made from looking at well-known methods or experimental techniques in new ways. This is the basis for new research from Dr. Alan Jamison, a faculty member at the Institute for Quantum Computing (IQC) and the University of Waterloo’s Department of Physics and Astronomy, and his collaborators at the Massachusetts Institute of Technology (MIT).

ETSI/IQC Quantum Safe Cryptography Conference 2024

ETSI and the Institute for Quantum Computing are pleased to announce the 10th ETSI/IQC Quantum Safe Cryptography Conference, taking place in Singapore on May 14-16, 2024. The event will be hosted by the Centre for Quantum Technologies, National University of Singapore.

This event was designed for members of the business, government, and research communities with a stake in cryptographic standardization to facilitate the knowledge exchange and collaboration required to transition cyber infrastructures and business practices to make them safe in an era with quantum computers. It aims to showcase both the most recent developments from industry and government and cutting-edge potential solutions coming out of the most recent research.

Biomimetic or nature-Inspired technologies are referring to the emerging fields where innovations are strongly inspired by the wisdom from nature or biological systems. Multiple levels of approaches are feasible from nature-inspiration – adaptation of how nature works, adoption of what nature provides, or replication of natural processes and functionalities for eco-friendly, sustainable, and highly efficient technologies. In this talk, nature-inspired approaches will be introduced for the nano-bio and nano-IT convergence research in the areas of nanostructure-cell interactions [1], nano-bio sensorics [2], biomimetic optical nanostructures [3], stretchable electronics [4], quantum plasmonics [5], and neuromorphic semiconductor technologies. Along with the research, recent efforts at Yonsei University will be introduced about the School of Integrated Technology where research and education are organically integrated for the technology convergence, and Yonsei Science Park where innovation ecosystem is established for IT-Bio Cluster Hub hosting Global Bio Campus and IBM quantum computer. This research was supported by the MSIT (Ministry of Science and ICT), Korea, under the ICT Consilience Creative program (IITP-2019-2017-0-01015) supervised by the IITP (Institute for Information & communications Technology Planning & Evaluation), the Ministry of trade, Industry and Energy (MOTIE) and Korea Institute for Advancement of Technology (KIAT) through the International Cooperative R&D program (Project No. P0019630) and by the Human Frontier Science Program (RGP0047/2019).

Last week, the Institute for Quantum Computing (IQC) welcomed over 20 promising postdoctoral fellows from around the world to Waterloo as part of the ninth annual Quantum Innovators workshop.

Split into two streams focused on theoretical and experimental research, speakers covered topics ranging from fault-tolerance and quantum cryptography to quantum defects in diamonds and atomic arrays, and many more topics spanning cutting edge quantum information research.

Online webinar through Microsoft Teams

The University of Waterloo and Mitacs will be holding a joint webinar on Thursday, November 23rd at 10am to share information about their new Globalink Research Award (Quantum stream), which provides funding for bilateral student travel with international university labs.

In this session, Amanda Green and Etienne Pineault, Senior Advisors with Mitacs, will provide information and updates on how to leverage Mitacs funding to build collaborative research projects with international university partners. 

Following the presentation, we will answer your questions about finding a partner, deciding on Mitacs eligibility and navigating program requirements (including how to work with our team to submit successful funding applications). Regan Child, International Grants and Contracts Manager with the Office of Research, will be on hand to offer assistance.

Problems based on the structure of graphs -- for example finding cliques, independent sets, or colourings -- are of fundamental importance in classical complexity. It is well motivated to consider similar problems about quantum graphs, which are an operator system generalisation of graphs. Defining well-formulated decision problems for quantum graphs faces several technical challenges, and consequently the connections between quantum graphs and complexity have been underexplored.

In this work, we introduce and study the clique problem for quantum graphs. Our approach utilizes a well-known connection between quantum graphs and quantum channels. The inputs for our problems are presented as quantum channels induced by circuits, which implicitly determine a corresponding quantum graph. We also use this approach to reimagine the clique and independent set problems for classical graphs, by taking the inputs to be circuits of deterministic or noisy channels which implicitly determine confusability graphs. We show that, by varying the collection of channels in the language, these give rise to complete problems for the classes NP, MA, QMA, and QMA(2). In this way, we exhibit a classical complexity problem whose natural quantisation is QMA(2), rather than QMA, which is commonly assumed.       

To prove the results in the quantum case, we make use of methods inspired by self-testing. To illustrate the utility of our techniques, we include a new proof of the reduction of QMA(k) to QMA(2) via cliques for quantum graphs. We also study the complexity of a version of the independent set problem for quantum graphs, and provide preliminary evidence that it may be in general weaker in complexity, contrasting to the classical case where the clique and independent set problems are equivalent.
