Node-to-node entanglement is the crucial resource in a quantum network and it is therefore of prime importance to have its fidelity and efficiency well under control. In Delft, we have done a rigorous study of entanglement generation between two Nitrogen-Vacancy quantum network nodes and shed light on the influcence of various parameters during entanglement generation. The gained insights give a route for future improvements of entangled state generation. Have a look at our detailed experimental and theoretical investigation, published today in New Journal of Physics:
