Coplanar Waveguide Resonators for Circuit Quantum Electrodynamics
M. Göppl, A. Fragner, M. Baur +7
We have designed and fabricated superconducting coplanar waveguide resonators with fundamental frequencies from 2 to and loaded quality factors ranging from a few hund…
Proposal for manipulating and detecting spin and orbital states of trapped electrons on helium using cavity quantum electrodynamics
D. I. Schuster, A. Fragner, M. I. Dykman +2
We propose to couple an on-chip high finesse superconducting cavity to the lateral-motion and spin state of a single electron trapped on the surface of superfluid helium. We estima…
Coupling an ensemble of electrons on superfluid helium to a superconducting circuit
Ge Yang, A. Fragner, G. Koolstra +4
The quantized lateral motional states and the spin states of electrons trapped on the surface of superfluid helium have been proposed as basic building blocks of a scalable quantum…
Observation of Non-Exponential Orbital Electron Capture Decays of Hydrogen-Like Pr and Pm Ions
Yu. A. Litvinov, F. Bosch, N. Winckler +37
We report on time-modulated two-body weak decays observed in the orbital electron capture of hydrogen-like Pr and Pm ions coasting in an ion storage…
Measurement of the $β^+$ and orbital electron-capture decay rates in fully-ionized, hydrogen-like, and helium-like Pr ions
Yu. A. Litvinov, F. Bosch, H. Geissel +39
We report on the first measurement of the $β^+$- and orbital electron capture decay rates of Pr nuclei with the most simple electron configurations: bare nuclei, hydrogen-…
Comment on the paper "Search for oscillation of the electron-capture decay probability of Pm" at arXiv:0807.0649v1
Yu. A. Litvinov, F. Bosch, N. Winckler +36
It is argued that orbital electron-capture decays of neutral Pm atoms implanted into the lattice of a solid (LBNL experiment) do not fulfil the constraints of true two-body…
