Sarah Burke is an Associate Professor in the Department of Physics and Astronomy at the University of British Columbia. She obtained her PhD from the University of McGill in 2009 and joined UBC in 2010. The principal aim of her research is to build an understanding of important electronic and optoelectronic processes in a wide range of materials from the atomic scale up. In particular, the role of interfaces in organic and nanoscale materials is often of crucial importance for applications oriented processes, yet is frequently not fully understood. Scanning probe microscopy offers the ability to investigate such interfaces at the atomic level. Dr. Burke’s research makes use of scanning probe microscopy (SPM) techniques including atomic force microscopy (AFM) and scanning tunnelling microscopy (STM) in ultrahigh vacuum (UHV) and at low temperatures (~4K). This clean, low-temperature environment allows the characterization of well defined systems, with sufficiently high energy resolution for most organic and nanoscale systems of interest, and with the level of stability required to achieve measurements on individual nanostructures.
The most ambitious application for silicon photonics – Chrostowski’s expertise – is in quantum computing. Silicon photonic approaches offer the potential for scaling to millions of qubits owing to the small device size and wafer-scale manufacturing. Chrostowski’s research is focused on developing the ingredients necessary to build a scalable fault-tolerant QC, including designing novel nanophotonic components for quantum information processing (lasers, single photon sources and detectors, spin qubit to photon coupling using resonators, optical switches, optical interconnects and low-loss coupling to the outside world), developing novel fabrication techniques, and building experimental apparatus for experimenting with quantum photonic circuits at cryogenic temperatures. Chrostowski was the Program Director of the NSERC CREATE Silicon Electronic-Photonic Integrated Circuits (Si-EPIC) research training program, which has expanded into a fabrication consortium, SiEPICfab (www.siepic.ubc.ca), and is the Program Director of the NSERC CREATE Quantum Computing program. He is a collaborator on the Canada Fund for Innovation (CFI) / BCKDF project, ‘The Silicon Quantum Leap: Tools for Building a Universal Quantum Computer’, and his NSERC Discovery Grant is “Silicon Photonics for Quantum Computing”.
Prototype “noisy” quantum computers based on several different technologies are now accessible over the cloud. However, the level of noise is often 10-100 times higher than the error correction threshold, hindering demonstrations of quantum advantage over conventional computers. The de Sousa research group is addressing this problem in both the hardware and software fronts. In hardware, the group is developing theory to elucidate the origin of noise and decoherence in the materials and devices used to build quantum computers. These theories are being compared to experiments at universities and companies around the world. In software, the research group is developing algorithms to benchmark and mitigate noise, and is using these findings to improve the output of quantum algorithms in cloud-based devices.
