X-ray circular dichroism measured by cross-polarization x-ray transient grating
Measuring natural circular dichroism in the x-ray regime to extract stereochemical information from chiral molecules in solution remains a challenge. This is primarily due to technical limitations of the existing synchrotron sources, which hinder acces…

Toward a Mølmer Sørensen gate with .9999 fidelity
Realistic fault-tolerant quantum computing at reasonable overhead requires two-qubit gates with the highest possible fidelity. Typically, an infidelity of is recommended in the literature. Focusing on the phase-sensitive architecture used in laboratori…

Quantum states and spectra of small cylindrical and toroidal lattices
We examine the spectrum and quantum states of small lattices with cylindrical and toroidal topology subject to a scalar gauge potential that introduces a position dependent phase in the inter-site coupling. Equivalency of gauges assumed in infinite lat…
