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…
Quantum control of a single molecular ion
David Holzapfel, Fabian Schmid, Nick Schwegler +5
Science is founded on the benchmarking of theoretical models against experimental measurements, with the challenge that for all but the simplest systems, the calculations required…
A 3-dimensional scanning trapped-ion probe
Tobias Sägesser, Shreyans Jain, Pavel Hrmo +6
Single-atom quantum sensors offer high spatial resolution and high sensitivity to electric and magnetic fields. Among them, trapped ions offer exceptional performance in sensing el…
Multi-zone trapped-ion qubit control in an integrated photonics QCCD device
Carmelo Mordini, Alfredo Ricci Vasquez, Yuto Motohashi +6
Multiplexed operations and extended coherent control over multiple trapping sites are fundamental requirements for a trapped-ion processor in a large scale architecture. Here we de…
Two-photon cooling of calcium atoms
Wojciech Adamczyk, Silvan Koch, Claudia Politi +6
We demonstrate sub-Doppler cooling of calcium atoms using a two-photon transition from the ground state to the upper state via the intermediate s…
