Scaling roadmap for modular trapped-ion QEC and lattice-surgery teleportation
César Benito, Alfredo Ricci Vasquez, Jonathan Home +4
We present a footprint study for the scaling of modular quantum error correction (QEC) protocols designed for triangular color codes, including a lattice-surgery-based logical tele…
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…
