Photon scattering rates in trapped ion qubits
ORAL
Abstract
In trapped-ion qubits, gates are often performed using two-photon stimulated Raman transitions. During such a transition, there is a risk of spontaneous photon scattering, which reduces the gate fidelity. Some past models of these scattering rates are suitable for moderate detunings but lose accuracy the further the laser is tuned from resonance. We present calculations of the scattering rates and show how including certain corrections changes the predictions of the model, in particular, lower scattering rates at large red detuning. Additionally, we discuss recent experimental work from our lab towards measuring the scattering rates in this far-detuned regime.
