Optical super-resolution sensing of a trapped ion's wave packet size
Martin Drechsler, Sebastian Wolf, Christian T. Schmiegelow +1
We demonstrate super-resolution optical sensing of the size of the wave packet of a single trapped ion. Our method extends the well known ground state depletion (GSD) technique to…
State dependent motional squeezing of a trapped ion: new method and applications
Martín Drechsler, María Belén Farías Nahuel Freitas, Christian Tomás Schmiegelow +1
We show that the motion of a cold trapped ion can be squeezed by modulating the intensity of a phase-stable optical lattice placed inside the trap. As this method is reversible and…
Compact embedded device for lock-in measurements and experiment active control
Marcelo Alejandro Luda, Martin Drechsler, Christian Tomás Schmiegelow +1
We present a multi-purpose toolkit for digital processing, acquisition and feedback control designed for physics labs. The kit provides in a compact device the functionalities of s…
Operation of a Microfabricated Planar Ion-Trap for Studies of a Yb-Rb Hybrid Quantum System
Abasalt Bahrami, Matthias Müller, Martin Drechsler +3
In order to study interactions of atomic ions with ultracold neutral atoms, it is important to have sub-m control over positioning ion crystals. Serving for this purpose, we int…
