A01 - Cooperative light emission and spatio-temporal photon correlations from trapped ion arrays

Organisationsmenü öffnen Organisationsmenü schließen

Summary

We aim at generating entangled states in trapped ion arrays based on projective measurements, i.e., via the detection of photons emitted by the ions in the far field. We plan to observe the quantum cooperative emission behavior of the entangled ion array and will use it for generating long lived entanglement, verifying the entanglement by quantum state tomography. Exploiting the cooperative photon emission, we will implement quantum enhanced imaging algorithms and test them by resolving impurity ions, structural defects and phase transitions of the ion array, eventually observing quantum phase transitions.
