Summary
Fault-tolerance is essential to the performance of quantum technologies, but known schemes are extremely resource intensive. Thus, improving existing schemes or inventing new schemes is of central importance. This joint project is based on the realization that fault-tolerance schemes make use of symmetries in fundamental ways, and that studying the problem of fault tolerance broadly from a symmetry perspective may offer valuable insights. We will do so by focusing on fault-tolerance and control-error mitigation primitives that make explicit use of symmetries, and unveil fundamental connections between the two. This involves the study of decoherence and error control, and measures that counteract them in two settings: fault-tolerant universal quantum computation (FTQC) using magic state distillation; and computational phases of matter. We will address which types of symmetries lead to computationally universal phases of matter, and the minimum operational cost of fault-tolerant universal quantum computation. This work is a collaboration between the research groups of David Poulin, Robert Raussendorf, and Beni Yoshida from the Université de Sherbrooke, University of British Columbia and the Perimeter Institute, respectively. Results from this project will shed light on which order parameters of condensed matter systems are important for quantum information processing and quantum sensing, and how to assess and reduce the overhead requirements for fault-tolerant quantum computation via understanding the process of magic-state distillation.

Portable Quantum Dot Measurement System
Summary Detecting heavy metals in water is essential to ensure clean drinking water and appropriate regulatory decisions following an accident (e.g., a spill) or an emergency. Traditionally, high-sensitivity detection of heavy metals requires bulky and costly (to purchase and operate) lab-based instruments. We propose developing a palm-sized, element-specific, highly-sensitive, battery-operated, smartphone-controlled system for on-site measurement […]

Identifying the Potential of Quantum Dots to Detect and Disrupt Tau Protein Aggregation in Alzheimer’s Disease
Specific tests for Alzheimer’s disease (AD) diagnosis are currently unavailable, despite AD being the leading cause of dementia. One hallmark of AD progression is the aggregation of tau proteins into paired helical filaments and neurofibrillary tangles, which is accelerated by the hyperphosphorylation of Tau proteins. However, the mechanism by which the hyperphosphorylated tau accelerates protein […]
