Welcome to the Institute for Quantum Computing

Faculty positions - apply nowThe Institute for Quantum Computing (IQC) is a scientific research institute at the University of Waterloo. The research happening at IQC harnesses the quantum laws of nature in order to develop powerful new technologies and drive future economies.

If you are new to all things quantum, you may want to see our Quantum computing 101 page. It will provide you with a quickstart guide on quantum computing to help you understand some of the research that happens at IQC.

    New $2.7 million project funded by Department of National Defence will develop technology for quantum radar.

    Stealth aircraft in the Canadian arctic will be no match for a new quantum radar system.

    Researchers at the University of Waterloo are developing a new technology that promises to help radar operators cut through heavy background noise and isolate objects —including stealth aircraft and missiles— with unparalleled accuracy.

  3. Apr. 4, 2018The ride of your life: surviving and thriving in the startup worldThe cell phone chip Manku developed to see radio frequency.

    The concept for his latest startup is something straight out of a superhero movie. Just like Batman used high-frequency sonar signals from millions of cell phones to visualize the location of villains throughout Gotham City in Dark Knight, entrepreneur Taj Manku is developing new software that could soon allow our cell phones to see in the dark.

  1. Apr. 23, 2018Probing many-body interactions using entangled photons: theory and thoughts for experiments.

    Eric Bittner, University of Houston

    Entangled photons offer an exquisite probe to correlated dynamics within a material system. In my talk I shall discuss some recent experiments and our theoretical investigations into developing an input/output scattering theory approach that connects an incoming photon Fock state to an outgoing Fock state, treating both the internal (material) and photon dynamics on a consistent footing. As proof of concept, we show how entangled photons can probe the inner workings of a model system undergoing spontaneous symmetry breaking.

  2. Apr. 24, 2018Quantum Computing - Dissipative Quantum Search

    PhD Seminar

    Chunhao Wang, PhD candidate

    David R. Cheriton School of Computer Science

    We give a dissipative quantum search algorithm that is based on a novel dissipative query model. If there are $N$ items and $M$ of them are marked, this algorithm performs a fixed-point quantum search using $O(\sqrt{N/M}\log(1/\epsilon))$ queries with error bounded by $\epsilon$. In addition, we present a continuous-time version of this algorithm in terms of Lindblad evolution.

  3. Apr. 24, 2018Quantum Computing - A Quantum Algorithm for Simulating Non-sparse Hamiltonians

    PhD Seminar

    Chunhao Wang, PhD candidate

    David R. Cheriton School of Computer Science

    We present a quantum algorithm for simulating the dynamics of Hamiltonians that are not necessarily sparse. Our algorithm is based on the assumption that the entries of the Hamiltonian are stored in a data structure that allows for the efficient preparation of states that encode the rows of the Hamiltonian. We use a linear combination of quantum walks to achieve a poly-logarithmic dependence on the precision.

  1. Nov. 8, 2016Launching QUANTUM: The ExhibitionSpecial guests at the launch of QUANTUM: The Exhibition holding a sign with the hashtag #quantumkw

    On August 30, Martin Laforest wrote a blog post about how to create a 4,000 square foot museum exhibition about an invisible science. That exhibition, QUANTUM: The Exhibition, came to life at THEMUSEUM for an invitation-only premiere on October 13, 2016 and then for the general public the next day.

  2. Oct. 11, 2016Alumna Sarah Sheldon on the IBM Quantum ExperienceSarah Sheldon with the USEQIP students

    On Tuesday, June 7, 24 students attending the Undergraduate School on Experimental Quantum Information Processing (USEQIP) at the Institute for Quantum Computing (IQC) used the IBM Quantum Experience to test algorithms that they were learning about in the classroom. Former IQC  PhD student, Dr. Sarah Sheldon, now a research staff member at the IBM T.J. Watson Research Center, introduced the students to the platform, assisted them in working through examples and described the inner workings of IBM’s quantum processor.

Norbert Lütkenhaus

Faculty, Professor

Norbert Lütkenhaus studied at the Rheinisch-Westfälische Technische Hochschule Aachen (RWTH Aachen) and the Ludwig Maximilian University (LMU) of Munich, from which he graduated with a thesis in general relativity.

He then changed the field to study quantum optics and quantum cryptography under the supervision of Stephen M.
