    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.

    QUANTUM + Pop Culture

    “Quantum physics” has taken its position with “rocket science” in pop culture as a shorthand for frighteningly complicated science. Quantum physics has also taken on a sort of magical connotation in fiction, with features like entanglement, superposition, and tunneling spurring imagination. But where does the science draw the line? How much is joyful speculation, and how much is disregard for reality? And if it’s always seen as either magical or scary, how does that affect the perception of quantum science?

  2. Nov. 19, 2018Quantum proof systems for iterated exponential time, and beyond

    Henry Yuen, University of Toronto

    An outstanding open question in quantum information theory concerns the computational complexity of nonlocal games. in a nonlocal game, a classical verifier interacts with multiple players that cannot communicate, but are allowed to share entanglement. In a recent breakthrough result, Slofstra showed that the following problem is undecidable: given a nonlocal game, is there a quantum strategy for the players to win with probability 1?
