Reversing Hydride Ion Formation in Quantum Information Experiments with Be${}^{+}$

Brian C. Sawyer, Justin G. Bohnet, Joseph W. Britton +1

We demonstrate photodissociation of BeH${}^{+}$ ions within a Coulomb crystal of thousands of ${}^9$Be${}^{+}$ ions confined in a Penning trap. Because BeH${}^{+}$ ions are created via exothermi…
