CQIQC

CQIQC is tasked with promoting research collaborations in the rapidly evolving interdisciplinary fields of quantum information and quantum control. CQIQC's activities at the University of Toronto encompass the Departments of Chemistry, Physics, Mathematics, Computer Science, Electrical Engineering, and Materials Science.

The Center was established in April 2004 with internal funding from the President of the University of Toronto, the Vice-President of Research and Associate Provost, the Dean of the Faculty of Arts & Science, and the Dean of the Faculty of Engineering. CQIQC funds endowed postdoctoral fellowships and summer student scholarships, organizes conferences, workshops and summer schools, coordinates the development and teaching of graduate courses in quantum science, and runs a seminar series. It also sponsors the biennial John Stewart Bell Prize for Research on Fundamental Issues in Quantum Mechanics and their Applications.

We encourage the UofT community to join us. To sign up to our mail list and participate in our activities, please contact quantum@utoronto.ca or visit us at LinkedIn.

Research Areas

CQIQC members are involved in a variety of theoretical and experimental activities, including coherent control, quantum optics, quantum cryptography, quantum decoherence-control, and quantum algorithms.

Recent Publications

The upper panel shows the T−V phase diagram for the three-orbital SYK model in the grand canonical ensemble. The lower shows the orbital-resolved density ns(T) and the total density n(T)=∑sns as a function of temperature for V=0.8 and 1.2.
Orbital selective order and ℤ3 Potts nematicity from a non-Fermi liquid
The breaking of the crystalline rotational symmetry for electrons in solids, termed “electronic nematic order” in analogy with liquid crystals, has been reported in diverse quantum materials ranging from semiconductor two-dimensional (2D) electron gases in the quantum Hall regime to unconventional superconductors such as heavy-fermion systems , CuO-, and Fe-based superconductors , and disordered Sr3⁢Ru2⁢O7.
Brumer_Multichannel Quantum Defect
Multichannel Quantum Defect Theory with a Frame Transformation for Ultracold Atom-Molecule Collisions in Magnetic Fields
Recent advances in cooling and trapping diatomic and polyatomic molecules have established ultracold molecular gases as an emerging platform for quantum information science, ultracold chemistry, and precision searches for new physics beyond the standard model. The exquisite control over molecular degrees of freedom achieved in these experiments enables the exploration of novel regimes of ultracold chemical dynamics tunable by external electromagnetic fields.
Computational time required to complete the optimization as a function of the degree of the polynomial on CPU vs GPU.
Generalized Quantum Signal Processing
The majority of prominent quantum algorithms, such as Hamiltonian simulation, quantum search, and factoring, can be fundamentally reduced to the central task of implementing a matrix function of a Hamiltonian. Quantum signal processing (QSP) currently stand as the most efficient technique for implementing such functions of block-encoded matrices.
Quantum Calculation of Photon Pair Generation_Sipe
Quantum Calculation of Photon Pair Generation in Quasi-phase Matched AlGaAs Microrings
Spontaneous parametric down-conversion (SPDC) is routinely used to create entangled photon pairs. Generation rates are limited by χ(2) magnitudes and phase matching issues, but in integrated structures the first limitation can be alleviated by using ring resonators to increase the local field intensity, and the second by a “built-in” quasi- phase matching (QPM) condition that is present for microrings fabricated out of III-V semiconductors
