Aßmann, Tracking quantum coherence in polariton condensates with time-resolved tomography, submitted. arXiv preprint arXiv:2209.07129 (2022)</p> <p>Long-term quantum coherence constitutes one of the main challenges when engineering quantum devices. However, easily accessible means to quantify complex decoherence mechanisms are not readily available, nor are sufficiently stable systems. We harness novel phase-space methods - expressed through non-Gaussian convolutions of highly singular Glauber-Sudarshan quasiprobabilities - to dynamically monitor quantum coherence in polariton condensates with significantly enhanced coherence times. Via intensity- and time-resolved reconstructions of such phase-space functions from homodyne detection data, we probe the systems's resourcefulness for quantum information processing up to the nanosecond regime. Our experimental findings are confirmed through numerical simulations for which we develop an approach that renders established algorithms compatible with our methodology. In contrast to commonly applied phase-space functions, our distributions can be directly sampled from measured data, including uncertainties, and yield a simple operational measure of quantum coherence via the distribution's variance in phase. Therefore, we present a broadly applicable framework and a platform to explore time-dependent quantum phenomena and resources.</p> <p>Funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) – SFB-Geschäftszeichen TRR142/3-2022 – Projektnummer 231447078, Projects A04 and C10.

Data Part 2: Megascale tomography of a quantum detector
<p>This contains the outcome matrix and the input state matrix, which are used to reconstruct the positive operator valued measures (POVMs) of the detector. The three POVM matrices based on reconstructions with no smoothing, standard next-neighbor smoothing and long-range smoothing as well as the POVMs based on the analytical model are included as well.</p> <p>Wigner function data based on the long-range smoothing and the analytical model POVMs are also included.</p> <p>The raw measurement data that is the basis of this processed data can be found here: <a href="https://doi.org/10.5281/zenodo.10803758" target="_blank" rel="noopener">https://doi.org/10.5281/zenodo.10803758</a></p>
