Applications of Quantum Information: From Black Hole Geometries to Gaussian Error Channels
When
-
In this work, we develop theoretical tools to explore
quantum correlations within the AdS/CFT framework. We examine the
holographic realization of optimized correlation measures in two-dimensional
thermal states corresponding to spacetimes with black hole horizons, enhancing
our understanding of how geometry encodes entanglement in AdS/CFT. We
further introduce cutoff-independent regularization techniques to compute these
entropies - addressing divergences due to infinite volume near the AdS

Programmable Bloch-Band Atom Interferometry in a Multidimensional Optical Lattice
When
-
Atom interferometers are exquisite sensors that have been used to perform inertial measurements with ever increasing precision. However, many worthy scientific endeavors present dynamically harsh environments and strict SWaP requirements that are challenging to accommodate for conventional atom interferometers. In this defense, I present the novel approach of Bloch-band interferometry, which confines Bose-condensed atoms to a multidimensional optical lattice for the entire interferometer sequence.
Quantum Effects Inside Rotating, Accreting Black Holes
When
-
Abstract: Models of rotating black holes generally possess not only an event horizon, which marks the point of no return, but also an inner horizon, beyond which lies an observable singularity and potentially a wormhole to a new universe. However, if any matter or radiation falls into the black hole, these sources of accretion will trigger an instability that may destroy the inner horizon and anything beyond.
Measuring How Students Measure
When
-
Abstract: Physics education research in undergraduate laboratory courses is vital to ensure that these courses achieve their learning goals, such as developing hands-on technical skills and mastering concepts and practices related to measurement uncertainty. In this talk, I cover my role in developing a research-based assessment instrument, the Survey of Physics Reasoning on Uncertainty Concepts in Experiments (SPRUCE).
A high optical access cryogenic optical tweezer array
When
-
Abstract: Arrays of single trapped neutral atoms are an important platform for quantum metrology, simulation, and information processing. Interacting Rydberg atom arrays have undergone rapid scaling in qubit numbers and improvements in coherent control in recent years. Placing Rydberg atoms inside a cryogenic environment is of interest for reducing background gas collisions and blackbody radiation-induced decay.
Tabletop Coherent Extreme Ultraviolet Metrology and Imaging of Nanostructures
When
-
Abstract: Nanoscale fabrication has progressed to the level where detailed near nanometer structure can be routinely produced. As fabrication scales shrink to atomistic scales, a corresponding need for high precision characterization is in demand. The use of extreme ultraviolet light (EUV) for patterning of small-scale features has seen considerable development and application in recent years.
Extreme Ultraviolet Spectroscopy of Ultrafast Excitations in Magnetic Alloys
When
-
The next generation of logic devices may rely on very fast switching of magnetic states. In this thesis, I utilize ultrafast pulsed lasers to measure and manipulate magnetic states on their fundamental timescales: ranging from few-femtoseconds spin-transfers in Heusler alloys to magnetization reorientations in ferrimagnets which take tens of picoseconds. I utilize high harmonic generation to produce a tabletop extreme ultraviolet probe for resonant measurements.
