AQP Seminar: Quantum Technology for Frequency Metrology

Aalto Quantum Physics Seminars (Hybrid). Speaker: Prof. Klemens Hammerer (Institute of Theoretical Physics, Leibniz University Hannover)


Optical atomic clocks based on cold trapped ions offer the possibility to use the sophisticated tools of quantum control developed for quantum information processing for new protocols in frequency metrology. I will present results on optimizing such protocols for tailored states and measurements for ion clocks. I will also discuss prospects and challenges for quantum-assisted protocols in optical atomic clocks in general.
