Alignment and Optimisation of Optical Tweezers on Trapped Ions
M. Mazzanti, C. Robalo Pereira, N. A. Diepeveen +7
This paper presents a routine to align an optical tweezer on a single trapped ion and use the ion as a probe to characterize the tweezer. We find a smallest tweezer waist of $2.3(2…
Trapped Ion Quantum Computing using Optical Tweezers and Electric Fields
M. Mazzanti, R. X. Schüssler, J. D. Arias Espinoza +3
We propose a new scalable architecture for trapped ion quantum computing that combines optical tweezers delivering qubit state-dependent local potentials with oscillating electric…
A high-fidelity method for a single-step -bit Toffoli gate in trapped ions
Juan Diego Arias Espinoza, Koen Groenland, Matteo Mazzanti +2
Conditional multi-qubit gates are a key component for elaborate quantum algorithms. In a recent work, Rasmussen et al. (Phys. Rev. A 101, 022308) proposed an efficient single-step…
Buffer gas cooling of a trapped ion to the quantum regime
T. Feldker, H. Fürst, H. Hirzler +5
Great advances in precision quantum measurement have been achieved with trapped ions and atomic gases at the lowest possible temperatures. These successes have inspired ideas to me…
Controlled long-range interactions between Rydberg atoms and ions
Thomas Secker, Rene Gerritsma, Alexander W. Glaetzle +1
We theoretically investigate trapped ions interacting with atoms that are coupled to Rydberg states. The strong polarizabilities of the Rydberg levels increases the interaction str…
Rydberg excitation of a single trapped ion
T. Feldker, P. Bachor, M. Stappel +4
We demonstrate excitation of a single trapped cold Ca ion to Rydberg levels by laser radiation in the vacuum-ultraviolet at 122 nm wavelength. Observed resonances are id…
Generalised Kronig-Penney model for ultracold atomic quantum systems
A. Negretti, R. Gerritsma, Z. Idziaszek +2
We study the properties of a quantum particle interacting with a one dimensional structure of equidistant scattering centres. We derive an analytical expression for the dispersion…
Quantum dynamics of an atomic double-well system interacting with a trapped ion
Jannis Joger, Antonio Negretti, Rene Gerritsma
We theoretically analyze the dynamics of an atomic double-well system with a single ion trapped in its center. We find that the atomic tunnelling rate between the wells depends bot…
Entangled states of trapped ions allow measuring the magnetic field gradient of a single atomic spin
F. Schmidt-Kaler, R. Gerritsma
Using trapped ions in an entangled state we propose detecting a magnetic dipole of a single atom at distance of a few m. This requires a measurement of the magnetic field gradie…
A bosonic Josephson junction controlled by a single trapped ion
R. Gerritsma, A. Negretti, H. Doerk +3
We theoretically investigate the properties of a double-well bosonic Josephson junction coupled to a single trapped ion. We find that the coupling between the wells can be controll…
