High-Fidelity Transport of Trapped-Ion Qubits in a Multi-Layer Array
Deviprasath Palani, Florian Hasse, Philip Kiefer +4
A variety of physical platforms are investigated for quantum control of many particles, and techniques are extended to access multiple dimensions. Here, we present our experimental…
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…
Spectroscopy and Directed Transport of Topological Solitons in Crystals of Trapped Ions
J. Brox, P. Kiefer, M. Bujak +2
We study experimentally and theoretically discrete solitons in crystalline structures consisting of several tens of laser-cooled ions confined in a radiofrequency trap. Resonantly…
