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.

High-Order Randomized Compiler for Hamiltonian Simulation
High-Order Randomized Compiler for Hamiltonian Simulation
Our work introduces a method called qSWIFT, a high-order randomized algorithm for Hamiltonian simulation. This method is a significant improvement over existing methods, such as qDRIFT, as it requires far fewer computational steps (or gates) to achieve the same level of precision. The qSWIFT algorithm is designed in such a way that the number of gates required does not depend on the number of terms in the Hamiltonian, making it more efficient for complex systems.

Spin Rotations in a Bose-Einstein Condensate Driven by Counterflow and Spin-Independent Interactions
Spin dynamics in cold atomic gases exhibit rich phenomena due to the interplay of particle interactions, quantum coherence, and particle statistics. In a Bose-Einstein condensate (BEC) with only contact interactions, spin dynamics can be induced by the spin dependence of the interaction strengths between particles. If interspin and intraspin interaction strengths are the same, on the other hand, there is only one scattering length, a.
Delta-T Flicker Noise Demonstrated with Molecular Junctions
Electronic flicker noise is the most abundant noise in electronic conductors. Here, we identify an unknown type of electronic flicker noise that is found when a temperature difference is applied across a nanoscale conductor. While this noise can be a performance-limiting factor, on the positive side, it can detect temperature differences across a large variety of nanoscale conductors, down to atomic-scale junctions with no special setup requirements.

Quantum repeaters: from quantum networks to the quantum internet
A quantum internet is the holy grail of quantum information processing, enabling the deployment of a broad range of quantum technologies and protocols on a global scale. However, numerous challenges must be addressed before the quantum internet can become a reality.
