State-dependent Gaussian gate set using an optical tweezer for trapped ions
Philip Leindecker, Luka Milanovic, Tanja Behrle +5
We demonstrate a state-dependent Gaussian gate set on the motional modes of trapped Ca ions, realized with an optical tweezer. Dynamic control of the tweezer intensity a…
Quantum theory for phonon lasing and non-classical state generation in mixed-species and single trapped ions
David Baur, Tanja Behrle, Ivan Rojkov +4
In this article we present a comprehensive theoretical investigation of phonon lasing with mixed-species trapped ions, as demonstrated in [T. Behrle, Phys. Rev. Lett. 131 (2023)],…
Modular variable laser cooling for efficient entropy extraction
Brennan de Neeve, Thanh-Long Nguyen, Alexander Ferk +5
We propose and experimentally demonstrate a method for laser cooling an oscillator based on sequences of spin-state-dependent displacements followed by spin repumping. For a therma…
Low-excitation transport and separation of high-mass-ratio mixed-species ion chains
Francesco Lancellotti, Stephan Welte, Matteo Simoni +6
We demonstrate low-excitation transport and separation of two-ion crystals consisting of one beryllium and one calcium ion, with a high mass ratio of . The full separation inv…
A phonon laser in the quantum regime
T. Behrle, T. L. Nguyen, F. Reiter +7
We demonstrate a trapped-ion system with two competing dissipation channels, implemented independently on two ion species co-trapped in a Paul trap. By controlling coherent spin-os…
Error correction of a logical grid state qubit by dissipative pumping
Brennan de Neeve, Thanh Long Nguyen, Tanja Behrle +1
Stabilization of encoded logical qubits using quantum error correction is key to the realization of reliable quantum computers. While qubit codes require many physical systems to b…
Circuit quantum acoustodynamics with surface acoustic waves
R. Manenti, A. F. Kockum, A. Patterson +5
The experimental investigation of quantum devices incorporating mechanical resonators has opened up new frontiers in the study of quantum mechanics at a macroscopic level.…
Double-sided coaxial circuit QED with out-of-plane wiring
J. Rahamim, T. Behrle, M. J. Peterer +6
Superconducting circuits are well established as a strong candidate platform for the development of quantum computing. In order to advance to a practically useful level, architectu…
