Quantum materials that exhibit strong electron correlations lead to phenomena, such as superconductivity and topologically protected states, that are important for quantum computation, sensing, and other applications. For example, we may utilize symmetry protected topological states to make qubits that are robust against decoherence, while advances in high temperature superconductors may significantly reduce losses in power distribution. However, key gaps remain in our understanding of cuprates and other strongly correlated materials.
In this project we will develop an Angle Resolved Inverse Photoemission Spectroscopy (ARIPES) tool and use it to probe unoccupied electronic states of such materials. Our objectives are to identify the correct theoretical descriptions of cuprates and other correlated materials and search for hallmarks of topological materials, such as Dirac and Weyl nodes. Furthermore, with this tool we will produce momentum-resolved maps of the unoccupied bands. This project will develop Canada’s only operational ARIPES tool, and is expected to rapidly develop our understanding of quantum materials.
Topological Properties of Exciton-Polaritons in a Kagome Lattice as a Solid-state Quantum Simulator
Summary In this project, we build a solid-state quantum simulator for engineering a specific Hamiltonian. Quantum simulators are purpose-built devices with little to no need for error correction, thereby making this type of hardware less demanding than universal quantum computers. Our platform consists of exciton-polariton condensates in multiple quantum-wells sandwiched in a semiconductor Bragg […]

Cryo-CMOS to Control and Operate 2D Fault-Tolerant Qubit Network
Summary Large-scale, fault-tolerant quantum computation requires precise and stable control of individual qubits. This project will use complementary metal-oxide-semiconductor (CMOS) technology to provide a cost-effective scalable platform for reliable and high-density control infrastructure for silicon spin qubits. We will use sub-micron CMOS technology to address device and circuit-level challenges and explore the integration of […]
