We present a measurement of the branching fractions for decay from the long-lived $5D_{5/2}$ level in \Ba. The branching fraction for decay into the $6S_{1/2}$ ground state was found to be $0.846(25)_{\mathrm{stat}}(4)_{\mathrm{sys}}$. We also report an improved measurement of the $5D_{5/2}$ lifetime, $\tau_{5D_{5/2}}=31.2(0.9)$~s. Together these measurements provide the first experimental determination of transition rates for decay out of the $5D_{5/2}$ level. The low ($<7 \times 10^{-12… 21 Citations ## Figures and Tables from this paper • Physics • 2020 Branching fractions for decays from the$P_{3/2}$level in$^{138}$Ba$^+$have been measured with a single laser-cooled ion.

The lifetime of the long-lived 5d(2)D(5/2) level in Ba-138(+) ions was measured in trapped single ions and small ion crystals using continuous quantum jump spectroscopy. We find tau(D5/2) = 25.6(0.5)

The lifetime of the metastable 5d2D5/2 state has been measured for a single trapped Ba+ ion in a Paul trap in Ultra High Vacuum (UHV) in the 10−10 mbar pressure range. A total of 5046 individual
The Standard Model of particle physics describes the behavior of all known elementary particles. This theory is remarkably successful in explaining the dynamics of the subatomic world (see also the
Quantum information has typically focused on using 2-level qubits to perform simulation and computation. We propose to expand the number of levels for computation using qudits, where d > 2. Doing so
