Through its phenomenal ability to image soft tissues, magnetic resonance imaging (MRI) has revolutionized both clinical medicine and research biomedicine. Nowadays, MRI scanners used clinically have spatial resolutions in the range of 0.5 mm. This enables identification and monitoring of disease processes throughout the body and visualization of minute brain structures. Magnetic resonance microscopy (MRM) brings the resolution down to the micron scale, so that cells and parts of cells can be seen. Using ultrasensitive silicon nano-wired mechanical resonators, we are working to distinguish small ensembles of nuclear and electron spins. In doing so, we are striving to bring MR down to the nanometer scale, allowing imaging of single viral particles. Subsequently, extending the approach to the Angstrom scale, our goal is to demonstrate MR imaging of individual protein molecules.
Developing Tools for Quantum Characterization and Validation
Summary Coherence is essential for quantum computation; yet it introduces a unique sensitivity to any imperfections in hardware design, control systems, and the operating environment. Overcoming these sensitivities requires a hierarchy of strategies, ranging from optimization of the hardware architecture to software solutions including quantum error correction. Randomized Benchmarking Protocols are an important family of […]

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 […]

Quantum Simulations of Fundamental Interactions
Summary To address questions in modern physics such as “what is the structure of matter inside neutron stars?” we need better computational methods to evaluate the interplay of fundamental forces between elementary particles. To-date the response to such questions rests on numerical computer simulations that are inherently limited. In this project, we develop new theoretical […]
