abstract: "<p>Data underlying the research article "Spin-Photon Correlations from a Purcell-enhanced Diamond Nitrogen-Vacancy Center Coupled to an Open Microcavity". In this physics paper, we present an efficient spin-photon interface between a coherently controlled diamond nitrogen-vacancy center spin qubit and a fiber-based Fabry-Perot microcavity. We demonstrate resonant optical spin qubit initialization and readout as well as coherent spin qubit control with microwave pulses. In combination with the Purcell-enhanced readout transition we generate two-qubit and three-qubit spin-photon states and measure heralded Z-basis correlations between the photonic time-bin qubits and the spin qubit. The measurements are performed in a quantum optics laboratory.</p><p>The dataset contains the measured data and the python code to analyse and reproduce the figures shown in the text. The measurements are conducted with the Python 3 framework Quantum Measurement Infrastructure (QMI) and data is collected with Python-based data acquisition framework Quantify. The measured data is stored in individual hdf5 files, with a unique timestamp and identifier. Analysed data is stored in hdf5 files named processed dataset.</p><p>Please see the README.md file for instructions on how to analyse the data and reproduce the figures.</p>"
