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.

Recent Publications

Parametric hypersensitivity Article
Parametric hypersensitivity and transport in the steady-state open-system Holstein model
The behavior of open quantum systems is of great interest in many areas such as chemical dynamics, biological systems, and quantum computing . Due to environmental effects such as dissipation and driving, these systems can display nonequilibrium steady states (NESS) that differ significantly from the closed-system dynamics .
On propagation of information article
On propagation of information in quantum mechanics and maximal velocity bounds
The study of evolution of information in condensed matter physics is an active, robust area of research with many profound results. At the same time, perhaps due to the difficulty of experimental implementation, with the exception of a few works on quantum open systems, this fundamental issue was not tackled in the original setting of quantum mechanics, i.e. at zero particle density. In this paper, we address this subject in a systematic way.
Hamiltonian Learning Article
Hamiltonian Learning via Shadow Tomography of Pseudo- Choi States
Identifying the system Hamiltonian is a central problem in physics, as the Hamiltonian uniquely describes the dynamics of any closed quantum system. Additionally, as quantum computers evolve, the need to characterize errors in their behaviour is becoming increasingly important, and as a result, several classes of quantum certification protocols have been designed to ensure quantum devices behave as intended.
Opportunities and Challenges Article
Opportunities and Challenges in Quantum-Enhanced Optical Target Detection
Light is a powerful tool for target detection to determine the presence, distance, and physical properties of a target object. Compared to other transmitters of energy (e.g., microwave and acoustic waves), light offers unique advantages due to its high resolution and directionality. In recent years, the rapid development of miniaturized and integrated optical systems has also helped optical target detection systems meet the growing demands of emerging applications such as autonomous driving.
