  1. Oct. 29, 2018New methods to produce and detect optical and matter-wave spin-orbit statesPoincare and Bloch sphere isomorphism

    Researchers at the Institute for Quantum Computing (IQC) in collaboration with researchers at the National Institute for Standards and Technology (NIST) have developed a highly robust method for structuring light and matter waves, enhancing the powerful probing ability of neutrons.

  2. Oct. 18, 2018Constant-time quantum computers more powerful than classical counterpartsScientists prove there are certain problems that require only a fixed circuit depth when done on a quantum computer no matter ho

    Quantum computers can solve a linear algebra problem faster than classical computers, according to a new study published in Science. The finding proves that constant-depth quantum circuits are more powerful than their classical counterparts, and provides a new sense of how quantum technology will be a key to more powerful computing.

  3. Oct. 17, 2018Generating multiphoton entanglement on a superconducting chip

    A step further for secure quantum communication and scalable quantum computing

    A team of researchers at the Institute for Quantum Computing (IQC) generated three-photon entanglement on a superconducting chip using a new, scalable technique.

    The experiment, published in Physical Review Applied, could lead to advances in quantum communication protocols like secret sharing and in quantum computing power.

  1. Dec. 10, 2018Quantum Algorithms for Composed Functions With Shared Inputs

    Justin Thaler, Georgetown University

    The quantum query complexity of a function f measures how many bits of the input a quantum computer must look at in order to compute f. 

  2. Dec. 13, 2018Applied Mathematics Colloquium: Quantum Universe

    Neil Turok, Perimeter Institute

    Observations reveal the cosmos to be astonishingly simple, and yet deeply puzzling, on the largest accessible scales. Why is it so nearly symmetrical? Why is there a cosmological constant (or dark energy) and what fixes its value? How did everything we see emerge from a singular “point” in the past?

    Wavelength selective thermal emitters using nitride quantum wells and photonic crystals

    Dr. Dongyeon Daniel Kang, Kyoto University

    Wavelength selective thermal emitters are highly desired for the development of the compact/energy-efficient spectroscopic sensing systems capable of detecting various gases such as COx, CH4, and NOx, which are strongly needed in environmental science, medical care, and other industrial applications. In addition, for the latter applications, dynamic control of thermal emission intensity is important for such emitters because synchronous detection can increase the signal-to-noise ratio significantly.

Raymond Laflamme

Faculty, Canada Research Chair

Raymond Laflamme was born in Quebec City and did his undergraduate studies in Physics at Université Laval. He then moved to Cambridge, England, where he survived Part III of Mathematical Tripos before earning his PhD in the Department of Applied Mathematics and Theoretical Physics (DAMTP) under the direction of Stephen Hawking. Laflamme and Don Page are responsible for having changed Hawking's mind on the direction of time in a contracting Universe (as described in Hawking’s best-seller "A Brief History of Time").
