Spontaneous emission has limited our previous work. We show theoretically that in the high-field regime, the two gates perform comparably well. We also examine how detuning the laser beams between the Zeeman levels in the P3/2 manifold at high fields enables us to improve upon operations with detuning between the P1/2 and P3/2 manifolds and explore if this protocol can be extended to lower fields. Finally, we compare the possible fidelity of entangling gates in high and low magnetic fields.
