The coherent control and communication between distant qubits is essential for quantum information processing. A sensor scheme based on an atomic sized quantum sensor, the nitrogen vacancy (NV) center in diamond, pushes the sensitivity to the local read out of single spins. Due to its access to various transitions in the optical and microwave frequency domain the coupling between single NV centers and electron spin networks can be observed in a reliable way [1]. Here, we present electron spin resonance studies on doubly spin labeled polypeptides and endohedral N@C60 controlled by shallow NV centers. For this, we employ an UHV cryo-microscopy setup [2]. By locally coupling our atomic-sized sensor to interacting spins we are able to investigate transfer mechanisms through spin networks.
