Quantum jump dynamics in a trapped barium ion

We are investigating the dynamics of quantum jumps and have set up a system to study them using singly trapped barium ions. Our system is a modified Paul trap containing a parabolic mirror, which allows for light collection from 39\% of the solid angle surrounding the trapped barium ion. This high light collection gives us the ability to quickly detect when a quantum jump occurs. \par Following the work of Minev et al\footnote{Minev, Z. K., et al. "To catch and reverse a quantum jump mid-flight." arXiv preprint arXiv:1803.00545 (2018).} where they demonstrated the ability to predict quantum jumps in a superconducting artificial atom, we plan to investigate the occurrence of quantum jumps in a single trapped barium ion.
