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.

How much time does a photon spend as an atomic excitation before being transmitted through a cloud of atoms?
The propagation of a beam of light through a cloud of two-level atoms is among the most ubiquitous phenomena in atomic, molecular, and optical physics. Understanding the coherent effects of light on atoms, and the slowing, refraction, absorption, and scattering of light by atoms underlies the entire field. It has been pivotal in the conceptual development of Quantum Optics from Einstein’s early analysis of wave-particle duality up through today’s studies of cavity QED, nonclassical states...

Application-level benchmarking of quantum computers using nonlocal game strategies
Running simple instances of quantum algorithms with a provable advantage is difficult given the current state of quantum hardware. For this reason, it is important to develop benchmarking tools and techniques that can test and validate the unique aspects of quantum hardware that are consistent with the predictions of quantum theory.

Suppression of decoherence dynamics by a dissipative bath at strong coupling
Quantum coherence is an important property of quantum mechanical systems, which describes the “quantumness” of the system, or the ability for quantum states to interfere, and the system to exhibit nonclassical behaviors such as quantum entanglement. Quantum coherences have a wide range of applications : In quantum computing, it is essential to maintain superpositions and entanglement for quantum speedup in algorithms.

Effects of time dependence in the second order coherence of pulsed light
Photon bunching is the phenomena of photodetector counts clustering together in time more than can be expected from independently (Poissonian) distributed photocounts. The measurement of photocount time distributions at a single photon detector gave an intuitive interpretation to the unintuitive intensity correlation results of Hanbury Brown and Twiss.
