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 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.

Discovery of charge order in a cuprate Mott insulator
High-temperature superconductivity (HTS) and charge density waves (CDW) are two prominent types of quantum electronic order that occur in cuprates. Using x-ray spectroscopy, muon spin rotation and electrical transport measurements on a special family of lanthanide-based cuprates, the authors have discovered a continuous evolution of the CDW order from the superconducting regime to the Mott insulator limit, indicating both HTS and CDW to be emergent phenomena of strong-correlation physics.

A Hybrid Quantum-Classical Algorithm for Multichannel Quantum Scattering of Atoms and Molecules
This paper proposes a hybrid quantum-classical algorithm for solving the time-independent Schrödinger equation for atomic and molecular collisions. It discovers that calculating scattering cross sections and rates for complex molecular collisions on NISQ quantum processors is possible. Some potential applications of their research include: scalable digital quantum computation of gas-phase bimolecular collisions and reactions of relevance to astrochemistry and ultracold chemistry.
Fully Passive Quantum Key Distribution
The authors have proposed a Quantum Key Distribution (QKD) scheme without any modulators, which removes a major source of side channels on QKD sources. The proposal suggests a new type of passive linear optical QKD source. This breakthrough can help improve the security of practical QKD systems.

Measurement optimization techniques for excited electronic states in near-term quantum computing algorithms
The authors investigate how to improve the quantum measurement efficiency for the variational quantum eigensolver (VQE). Since VQE is one of the most popular near-term quantum algorithms for solving the electronic structure problem. They achieve this goal by investigating various measurement techniques to two widely used excited state VQE algorithms: multistate contraction and quantum subspace expansion.
