Robust polarization gradient cooling of trapped ions
New Journal of Physics, 2022 We implement three-dimensional polarization gradient cooling (PGC) of trapped ions. Counter-propagating laser beams near 393 nm impinge in lin ⊥ lin configuration, at a frequency below the S _1/2 to P _3/2 resonance in ^40 Ca ^+ .

Sympathetic and swap cooling of trapped ions by cold atoms in a MOT [PDF]
, 2011 A mixed system of cooled and trapped, ions and atoms, paves the way for ion assisted cold chemistry and novel many body studies. Due to the different individual trapping mechanisms, trapped atoms are significantly colder than trapped ions, therefore in ...

Quantum dynamics of cold trapped ions, with application to quantum computation [PDF]
, 1997 The theory of interactions between lasers and cold trapped ions as it pertains to the design of Cirac-Zoller quantum computers is discussed. The mean positions of the trapped ions, the eigenvalues and eigenmodes of the ions' oscillations, the magnitude ...

Trapping of highly charged ions with an electrostatic ion trap [PDF]
Journal of Physics: Conference Series, 2009 In the current contribution, we present our first results with an electrostatic ion trap which has been constructed at LKB (Laboratoire Kastler Brossel) in collaboration with the Weizmann institute. The electrostatic ion trap is composed of two coaxial electrostatic mirrors, working for charged particles in the same way as a Fabry-Perot interferometer ...

High-Stability Cryogenic System for Quantum Computing With Compact Packaged Ion Traps
IEEE Transactions on Quantum Engineering, 2022 Cryogenic environments benefit ion trapping experiments by offering lower motional heating rates, collision energies, and an ultrahigh vacuum (UHV) environment for maintaining long ion chains for extended periods of time.

Engineering generalized Gibbs ensembles with trapped ions
Physical Review Research, 2021 The concept of generalized Gibbs ensembles (GGEs) has been introduced to describe steady states of integrable models. Recent advances show that GGEs can also be stabilized in nearly integrable quantum systems when driven by external fields and open. Here,

Quantum Repeaters based on Single Trapped Ions [PDF]
, 2009 We analyze the performance of a quantum repeater protocol based on single trapped ions. At each node, single trapped ions embedded into high finesse cavities emit single photons whose polarization is entangled with the ion state.

Micromotion-enabled improvement of quantum logic gates with trapped ions
New Journal of Physics, 2017 The micromotion of ion crystals confined in Paul traps is usually considered an inconvenient nuisance, and is thus typically minimized in high-precision experiments such as high-fidelity quantum gates for quantum information processing (QIP).

EIT ground-state cooling of long ion strings [PDF]
, 2016 Electromagnetically-induced-transparency (EIT) cooling is a ground-state cooling technique for trapped particles. EIT offers a broader cooling range in frequency space compared to more established methods.

Fast separation of two trapped ions
New Journal of Physics, 2015 We design fast protocols to separate or recombine two ions in a segmented Paul trap. By inverse engineering the time evolution of the trapping potential composed of a harmonic and a quartic term, it is possible to perform these processes in a few ...
