Certifying Multilevel Coherence in the Motional State of a Trapped Ion
Ollie Corfield, Jake Lishman, Chungsun Lee +6
Quantum coherence is one of the clearest departures from classical physics, exhibited when a system is in a superposition of different basis states. Here the coherent superposition…
Coherence properties of highly-excited motional states of a trapped ion
Vincent Jarlaud, Pavel Hrmo, Manoj K. Joshi +1
We present a study of the coherence properties of a variety of motional states of a single ion confined in a Penning ion trap. We demonstrate that the motion of the ion has a coher…
Lifetimes and g-factors of the HFS states in H-like and Li-like bismuth
Volker Hannen, Jonas Vollbrecht, Zoran Andelkovic +23
The LIBELLE experiment performed at the experimental storage ring (ESR) at the GSI Helmholtz Center for Heavy Ion Research in Darmstadt, Germany, has successfully determined the gr…
Ion Coulomb Crystals
Richard C. Thompson
Ion Coulomb crystals (ICC), formed by atomic ions at low temperatures in radiofrequency and Penning ion traps, are structures that have remarkable properties and many applications.…
Resolved-sideband laser cooling in a Penning trap
J. F. Goodwin, G. Stutter, R. C. Thompson +1
We report the laser cooling of a single ion in a Penning trap to the motional ground state in one dimension. Cooling is performed in the strong binding limit on…
Trapped-ion quantum error-correcting protocols using only global operations
Joseph F. Goodwin, Benjamin J. Brown, Graham Stutter +3
Quantum error-correcting codes are many-body entangled states that are prepared and measured using complex sequences of entangling operations. Each element of such an entangling se…
Observation of the hyperfine transition in lithium-like Bismuth : Towards a test of QED in strong magnetic fields
Matthias Lochmann, Raphael Jöhren, Christopher Geppert +21
We performed a laser spectroscopic determination of the hyperfine splitting (HFS) of Li-like and repeated the measurement of the HFS of H-like $^{…
Physics with Trapped Charged Particles
Martina Knoop, Niels Madsen, Richard C. Thompson
Ion traps, which were first introduced in the late 1950s and early 1960s, have established themselves as indispensable tools in many areas of physics, chemistry and technology. Thi…
Laser cooling of externally produced Mg ions in a Penning trap for sympathetic cooling of highly charged ions
Z. Andelkovic, R. Cazan, W. Nörtershäuser +7
We have performed laser cooling of Mg ions confined in a Penning trap. The externally produced ions were captured in flight, stored and laser cooled. Laser-induced fluorescence was…
Fast shuttling of ions in a scalable Penning trap array
D. R. Crick, S. Donnellan, S. Ananthamurthy +2
We report on the design and testing of an array of Penning ion traps made from printed circuit board. The system enables fast shuttling of ions from one trapping zone to another, w…
Dynamics of axialized laser-cooled ions in a Penning trap
E. S. Phillips, R. J. Hendricks, A. M. Abdulla +5
We report the experimental characterization of axialization - a method of reducing the magnetron motion of a small number of ions stored in a Penning trap. This is an important ste…
Laser cooling in the Penning trap: an analytical model for cooling rates in the presence of an axializing field
R. J. Hendricks, E. S. Phillips, D. M. Segal +1
Ions stored in Penning traps may have useful applications in the field of quantum information processing. There are, however, difficulties associated with the laser cooling of one…
