      abstract     = {Scalable quantum technologies require an unprecedented
                      combination of precision and complexity for designing stable
                      structures of well-controllable quantum systems on the
                      nanoscale. It is a challenging task to find a suitable
                      elementary building block, of which a quantum network can be
                      comprised in a scalable way. We present the working
                      principle of such a basic unit, engineered using molecular
                      chemistry, whose collective control and readout are executed
                      using a nitrogen vacancy (NV) center in diamond. The basic
                      unit we investigate is a synthetic polyproline with electron
                      spins localized on attached molecular side groups separated
                      by a few nanometers. We demonstrate the collective readout
                      and coherent manipulation of very few (≤ 6) of these S =
                      1/2 electronic spin systems and access their direct dipolar
                      coupling tensor. Our results show that it is feasible to use
                      spin-labeled peptides as a resource for a molecular
                      qubit–based network, while at the same time providing
                      simple optical readout of single quantum states through NV
                      magnetometry. This work lays the foundation for building
                      arbitrary quantum networks using well-established chemistry
                      methods, which has many applications ranging from mapping
                      distances in single molecules to quantum information
                      processing.},
