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…
Optical trapping of ion Coulomb crystals
Julian Schmidt, Alexander Lambrecht, Pascal Weckesser +3
The electronic and motional degrees of freedom of trapped ions can be controlled and coherently coupled on the level of individual quanta. Assembling complex quantum systems ion by…
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…
Simulating spin-boson models with trapped ions
Andreas Lemmer, Cecilia Cormick, Dario Tamascelli +3
We propose a method to simulate the dynamics of spin-boson models with small crystals of trapped ions where the electronic degree of freedom of one ion is used to encode the spin w…
