Radio-frequency sideband cooling and sympathetic cooling of trapped ions in a static magnetic field gradient
Theeraphot Sriarunothai, Gouri Shankar Giri, Sabine Wölk +1
We report a detailed investigation on near-ground state cooling of one and two trapped atomic ions. We introduce a simple sideband cooling method for confined atoms and ions, using…
Speeding-up the decision making of a learning agent using an ion trap quantum processor
Theeraphot Sriarunothai, Sabine Wölk, Gouri Shankar Giri +4
We report a proof-of-principle experimental demonstration of the quantum speed-up for learning agents utilizing a small-scale quantum information processor based on radiofrequency-…
Estimation of gradients in quantum metrology
Sanah Altenburg, Michał Oszmaniec, Sabine Wölk +1
We develop a general theory to estimate magnetic field gradients in quantum metrology. We consider a system of particles distributed on a line whose internal degrees of freedom…
