Floquet-engineered vibrational dynamics in a two-dimensional array of trapped ions
Philip Kiefer, Frederick Hakelberg, Matthias Wittemer +4
We demonstrate Floquet engineering in a basic yet scalable 2D architecture of individually trapped and controlled ions. Local parametric modulations of detuned trapping potentials…
Particle pair creation by inflation of quantum vacuum fluctuations in an ion trap
Matthias Wittemer, Frederick Hakelberg, Philip Kiefer +5
The creation of matter and structure in our universe is currently described by an intricate interplay of quantum field theory and general relativity. Signatures of this process dur…
Interference in a Prototype of a two-dimensional Ion Trap Array Quantum Simulator
Frederick Hakelberg, Philip Kiefer, Matthias Wittemer +2
Quantum mechanics dominates various effects in modern research from miniaturizing electronics, up to potentially ruling solid-state physics, quantum chemistry and biology. To study…
Hybrid setup for stable magnetic fields enabling robust quantum control
Frederick Hakelberg, Philip Kiefer, Matthias Wittemer +2
Well controlled and highly stable magnetic fields are desired for a wide range of applications in physical research, including quantum metrology, sensing, information processing, a…
Probing Quantum Memory Effects with High Resolution
Matthias Wittemer, Govinda Clos, Heinz-Peter Breuer +2
Trapped atomic ions enable a precise quantification of the flow of information between internal and external degrees of freedom by employing a non-Markovianity measure [H.-P. Breue…
Motional-Mode Analysis of Trapped Ions
Henning Kalis, Frederick Hakelberg, Matthias Wittemer +3
We present two methods for characterization of motional-mode configurations that are generally applicable to the weak and strong-binding limit of single or multiple trapped atomic…
Freely configurable quantum simulator based on a two-dimensional array of individually trapped ions
Manuel Mielenz, Henning Kalis, Matthias Wittemer +7
A custom-built and precisely controlled quantum system may offer access to a fundamental understanding of another, less accessible system of interest. A universal quantum computer…
