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…
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…
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…
