Advances in SRF qubit architectures for quantum computing
Superconducting radio frequency (SRF) cavities provide an excellent platform for storing quantum information as quantum d-level systems (qudits) due to their exceptionally long lifetimes and large accessible Hilbert spaces. A common strategy to manipulate the states is to use a nonlinear element like a transmon. There are, however, several challenges to building a 3D SRF architecture while maintaining a long cavity lifetime. We demonstrate our successful integration of transmons with single-cell Nb SRF cavities and the ability to prepare several non-classical states. Finally, we discuss our strategies to improve the coherence times, gate schemes, and extend the system for building a multi-qudit quantum processor.

Optical Generation and Manipulation of Spin Qubits for Molecular Quantum Information Science (DE-SC0020199 Final Report)
Final Report containing published results and major accomplishments. Major accomplishments during this grant include elucidating the complex mechanisms of photoinduced ground-state electron spin polarization (PIESP) for these complexes. Several detailed studies relating molecular structure and PIESP are detailed. In addition, we have demonstrated polarization of two coupled ground-state spins with a single photon.

Testing the Jump Finding Code for NEXUS Qubit Analysis
We evaluate a new jump finding code to test the efficiency of this code in finding jumps of all sizes and understand how noise is mistaken for jumps and vice versa. We look at two parameters that impact the efficiency of the code. The two parameters, the jump threshold and smoothing, are then optimized to find the most efficient combination with the highest fraction of true positives and true negatives.
