Frequency metrology and precision spectroscopy with designed states and measurements (A09*)

• Subject Area: Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
• Term: since 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 274200144

This research project focuses on advancing atomic clocks and quantum measurements, with a primary goal of realizing entanglement-enhanced atomic clocks. Key aspects include developing optimal metrological protocols to balance interrogation time and decoherence, designing quantum gates for trapped ion clocks, exploring squeezing via Quantum-Nondemolition (QND) measurements in optical atomic clocks, and introducing sideband thermometry for cold ion crystals. Additionally, the study extends the treatment of mass defect in ion clocks and Penning traps.
