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.

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.
Models for spin-1/2 chains coupled to independent reservoirs
Bath-Engineering Magnetic Order in Quantum Spin Chains: An Analytic Mapping Approach
Spin chains offer a versatile platform for the study of quantum materials. They can capture a wide range of complex and exotic phenomena from magnetic effects to topological phases. These effects are observed in a variety of materials, including quantum magnets, spin liquids, and quantum wires. Beyond ideal models, in reality, environmental degrees of freedom such as lattice phonons or engineered cavity modes couple to the spin degrees of freedom.
Fully passive MDI-QKD setup.
Fully passive measurement-device-independent quantum key distribution
The laws of quantum mechanics ensure theoretically secure communication using quantum key distribution (QKD) between two parties. However, practically implementing QKD systems is still a challenge due to the lack of perfect equipment. Hence, physicists have been working on eliminating side channels arising from these imperfections.
Phase diagrame for OSST pairing as function
Finite-momentum and field-induced pairings in orbital-singlet spin-triplet superconductors
Superconductivity is conventionally understood as the condensation of electron pairs near the Fermi energy with momentum 𝐤 and −𝐤, i.e., a zero center-of-mass momentum, referred to as uniform pairing. A term in the Hamiltonian that breaks the degeneracy of the paired electrons generally suppresses the pairing.
