Dataset

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.

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.

Please see the README.md file for instructions on how to analyse the data and reproduce the figures.
