The achieved ion-photon entanglement fidelity is .84(1) and a violation of the CHSH Bell Signal is shown to be greater than $8\sigma$. The utilization of a novel trap type and a pulsed laser for excitation is discussed for improvement of the rate of heralded ion-ion entanglement. A side project measuring the branching fraction of the 5D$_{5/2}$ level in $^{138}$Ba$^{+}$ is also discussed. dc.format.mimetype application/pdf dc.language.iso en_US dc.rights none dc.subject dc.subject.other Quantum physics dc.subject.other Atomic physics dc.subject.other Physics dc.subject.other physics dc.title Toward a Loophole-Free Bell Inequality Violation with Barium Ions dc.type Thesis dc.embargo.terms Restrict to UW for 5 years -- then make Open Access dc.embargo.lift 2022-01-19T22:42:08Z
