	abstract = {Correlations are fundamental in describing many-body systems. However, in experiments, correlations are notoriously difficult to assess on a microscopic scale, especially for electron spins. Even though it is firmly established theoretically that the electrons in a Cooper pair(1) of a superconductor form maximally spin-entangled singlet states with opposite spin projections(2-4), no spin correlation experiments have been demonstrated so far. Here we report the direct measurement ofthe spin cross-correlations between the currents of a Cooper pair splitter(5-13), an electronic device that emits electrons originating from Cooper pairs. We use ferromagnetic split-gates(14-15), compatible with nearby superconducting structures, to individually spin polarize the transmissions ofthe quantum dots in the two electronic paths, which act astunable spin filters. The signals are detected in standard transport and in highly sensitive transconductance experiments. We find that the spin cross-correlation is negative, consistent with spin singlet emission, and deviates from the ideal value mostly due to the overlap ofthe Zeeman split quantum dot states. Our results demonstrate a new route to perform spin correlation experiments in nano-electronic devices, especially suitable for those relying on magnetic field sensitive superconducting elements, like triplet ortopologically non-trivial superconductors(16-)(18), orto perform Bell tests with massive particles(19-20).},

	abstract = {Cooper pair splitting (CPS) is a way to create spatially separated, entangled electron pairs. To this day, CPS is often identified in experiments as a spatial current correlation. However, such correlations can arise even in the absence of CPS, when a quantum dot is strongly coupled to the superconductor, and a subgap Shiba state is formed. Here, we present a detailed experimental characterization of those spatial current correlations, as the tunnel barrier strength between the quantum dot and the neighboring normal electrode is tuned. The correlation of the nonlocal signal and the barrier strength reveals a competition between CPS and the nonlocal probing of the Shiba state. We describe our experiment with a simple transport model and obtain the tunnel couplings of our device by fitting the model's prediction to the measured conductance correlation curve. Furthermore, we use our theory to extract the contribution of CPS to the nonlocal signal.},

	abstract = {Hybrid quantum dot-oscillator systems have become attractive platforms to inspect quantum coherence effects at the nanoscale. Here, we investigate a Cooper-pair splitter setup consisting of two quantum dots, each linearly coupled to a local resonator. The latter can be realized either by a microwave cavity or a nanomechanical resonator. Focusing on the subgap regime, we demonstrate that cross-Andreev reflection, through which Cooper pairs are split into both dots, can induce nonlocal correlations between the two resonators. Harnessing these correlations allows to establish and control a nonlocal photon transfer between them. The proposed scheme can act as a photonic valve with single-photon accuracy, with potential applications for quantum heat engines and refrigerators involving mesoscopic resonators.},
