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.

Deterministically separable polarization-entangled photons from battery-powered diode lasers
The development of entangled photon sources with high flux and fidelity is crucial for the future of quantum information processing. Polarization entanglement has been one of the most widely used degrees of freedom due to its ease of manipulation and state detection. Furthermore, the generation of broadband polarization-entangled photons leaves the frequency degree of freedom available for spectral multiplexing in quantum networks.

On propagation of information in quantum many-body systems
The finite speed of propagation of particles and fields is a fundamental law of nature. It provides powerful constraints in relativistic physics. It is remarkable that such constraints also effectively exist in non-relativistic quantum theory, the only quantum theory with a solid mathematical foundation and physical consistency.
Observation of String Article
Observation of string breaking on a (2 + 1)D Rydberg quantum simulator
The observation that certain fundamental particles, such as quarks, cannot be isolated but are instead bound in composite hadrons, such as protons or neutrons, is attributed to a phenomenon called confinement. According to quantum chromodynamics (QCD), an extensive amount of energy is stored in a flux string of gluon fields that confines, for example, a quark–anti-quark pair.
Crystal structure for the double perovskite system
Phonon-Driven Multipolar Dynamics in a Spin-Orbit Coupled Mott Insulator
Shaking electrons or atoms with light can induce remarkable nonequilibrium many body states in solid-state crystals as well as ultracold atoms. In recent years, rapid advances in ultrafast and THz optics have led to the ability to resonantly excite specific orbital transitions and phonon modes in solids , providing a distinct pathway to control broken symmetry states including ferroelectricity , superconductivity , and magnetism.
