New Measurement of the Electron Magnetic Moment and the Fine Structure Constant
TL;DR: A measurement using a one-electron quantum cyclotron gave the electron magnetic moment in Bohr magnetons, g/2=1.001 159 652 180 73 (28) [0.28 ppt], with an uncertainty 2.7 and 15 times smaller than for previous measurements in 2006 and 1987.
Journal ArticleDOI
New measurement of the electron magnetic moment using a one-electron quantum cyclotron.
TL;DR: The new g, with a quantum electrodynamics (QED) calculation, determines the fine structure constant with a 0.7 ppb uncertainty--10 times smaller than for atom-recoil determinations.
Journal ArticleDOI
Cavity control of a single-electron quantum cyclotron: Measuring the electron magnetic moment
TL;DR: In this paper, a one-electron quantum cyclotron was used to determine the electron magnetic moment, given by $g/2=1.001 159 652 180 73(28)[0.28\mathrm{ppt}]$ and the fine structure constant, $ensuremath{\alpha{{-}^{\ENSuremath{-1}1}=137.035 999 084(51)[ 0.37\mathm{ppb}]$.
Journal ArticleDOI
New Determination of the Fine Structure Constant from the Electron g Value and QED
TL;DR: A new measurement of g using a one-electron quantum cyclotron and a QED calculation involving 891 eighth-order Feynman diagrams determine alpha(-1) =137, which sets a limit on internal electron structure.
Journal ArticleDOI
Complete Methods Set for Scalable Ion Trap Quantum Information Processing

TL;DR: This work shows a combination of all of the fundamental elements required to perform scalable quantum computing through the use of qubits stored in the internal states of trapped atomic ions and quantified the repeatability of a multiple-qubit operation and observed no loss of performance despite qubit transport over macroscopic distances.
