    Invited Oral

    The precision of a quantum clock near zero temperature, depends on how it is driven and how it is measured. We investigate both limits to precision using quantum stochastic thermodynamics, and illustrate the results with examples (superconducting and nano mechanical). Of particular relevance is the nature of the measurement as the clock signal ultimately depends on estimating the fluctuations...

    Precision and Quantum Metrology with Atoms, Photons and Phonons
    Invited Oral

    A nuclear-spin-based rotation sensor is implemented based on simultaneous measurements with two nitrogen isotopes intrinsic to nitrogen-vacancy centers in diamond, employing a microwave-free technique with optical addressing of nuclear spins. Differential measurements suppress systematics related to magnetic-field and temperature variations.
