Summary
The scalability of quantum processors is limited by current error rates for single-qubit gates. By encoding more than a single bit of information within a single ion, multi-level “qudits” offer a promising method of increasing the information density within a quantum processor, and therefore minimizing the number of gates and associated error rates. In this project we seek to improve the capabilities of trapped ion quantum processors, implementing all of the basic tools required to perform quantum information processing with multi-level qudits. To-date there have been few experimental efforts directed towards this area and many of the basic operations – such as reliably distinguishing among all possible basis states in a single-shot measurement or performing deterministic entangling gates – have not yet been demonstrated. In this project, we will design and construct a laser system that will be used to perform coherent operations, and to implement and characterize high-fidelity single-qudit gates. These will form some of the world’s first laboratory demonstrations of quantum computing with multi-level qudits. Because our approach will allow more information to be encoded with fewer qudits, and folds some of the complexity of a given algorithm into the non-entangling operations, there is reason to believe that the use of multi-level qudits could bring dramatic improvements to the scalability of quantum processors.

Using Interactive Digital Storytelling to Represent Transformative Quantum Technologies in Augmented/Extended Reality Environments
Summary A major roadblock to the broader adoption of quantum technologies is the long learning curve associated with their seemingly abstract concepts. This often renders quantum technologies inaccessible to most audiences, especially through explanations using conventional scientific language. In this project, we develop novel methods of interactive digital storytelling – augmented and extended reality (AR/XR) […]

Line-Scanning optical coherence tomography system for in-vivo, non-invasive imaging of the cellular structure and blood perfusion of biological tissue
Summary Optical coherence tomography (OCT) is an optical imaging method that allows for in-vivo, non-invasive imaging of the structure and vasculature of biological tissue. Commercially available, clinical OCT systems utilize point-scanning method to acquire volumetric images over a large surface with typical frame rates of ~ 30 frames/ second. Since living biological tissue is constantly […]

Structured Light Applications in Vision Science
Eye diseases such as macular degeneration can have a devastating impact on quality of life. Early detection and treatment are thus crucial for preventing irreversible vision loss. A previous study found that the human eye can detect differences in ‘structured’ light beams. Such light beams are composed of a coherent superposition of differently polarized planar […]
