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…
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…
State-dependent control of the motional modes of trapped ions using an integrated optical lattice
Alfredo Ricci Vasquez, Carmelo Mordini, Daniel Kienzler +1
In this work we study the interaction of trapped ions with a state-dependent, high-intensity optical lattice formed above an ion trap chip using integrated photonics. We use a sing…
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…
Physical coherent cancellation of optical addressing crosstalk in a trapped-ion experiment
Jeremy Flannery, Roland Matt, Luca Huber +4
We present an experimental investigation of coherent crosstalk cancellation methods for light delivered to a linear ion chain cryogenic quantum register. The ions are individually…
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…
