A magnetic-field insensitive gate set for trapped-ion nuclear spin qubits
Jonathan Paul Home, Jeremy Flannery, Matteo Mazzanti +2
We outline a complete set of operations for manipulating nuclear spin qubits of trapped-ions stored in high magnetic fields such as required for Penning trapping, where the nuclear…
Non-linear cooling and control of a mechanical quantum harmonic oscillator
Matteo Simoni, Ivan Rojkov, Matteo Mazzanti +7
Non-linearities are a key feature allowing non-classical control of quantum harmonic oscillators. However, when non-linearities are strong, designing protocols for control is often…
Quadratic spin-phonon coupling and bipolarons in trapped ions
L. P. H. Gallagher, M. Mazzanti, Z. E. D. Ackerman +3
We consider the quantum simulation of quadratic spin-phonon coupling in a crystal of trapped ions. The coupling is implemented using tightly focused optical tweezers on each ion th…
Non-paraxial effects on laser-qubit operations
L. P. H. Gallagher, M. Mazzanti, Z. E. D. Ackerman +3
Tightly-focused laser beams, or optical tweezers, are essential for analogue and digital quantum simulation with neutral atoms and trapped ions. Despite this, most of the current i…
Single ion spectroscopy of four metastable state clear-out transitions in Yb II: isotope shifts and hyperfine structure
N. A. Diepeveen, C. Robalo Pereira, M. Mazzanti +5
We present spectroscopic data for four metastable state clear-out transitions between 399 nm and 412 nm for all even long-lived isotopes of Yb as well as their hyperfine struct…
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 the Magnus Effect
M. Mazzanti, R. Gerritsma, R. J. C. Spreeuw +1
We consider the implementation of quantum logic gates in trapped ions using tightly focused optical tweezers. Strong polarization gradients near the tweezer focus lead to qubit-sta…
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…
Engineering spin-spin interactions with optical tweezers in trapped ions
Juan Diego Arias Espinoza, Matteo Mazzanti, Katya Fouka +5
We propose a new method for generating programmable interactions in one- and two-dimensional trapped-ion quantum simulators. Here we consider the use of optical tweezers to enginee…
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…
Experimental setup for studying an ultracold mixture of trapped Yb-Li
H. Hirzler, T. Feldker, H. Fürst +7
We describe and characterize an experimental apparatus that has been used to study interactions between ultracold lithium atoms and ytterbium ions. The preparation of ultracold clo…
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…
