The structure of the work plan and the inter-relation between its components is shown in the figure below. Tasks are organized into seven scientific/technological work packages (WPs) plus one WP devoted to the management of the project. Work towards each of the two main breakthroughs, namely the realization of QECC in molecules and the attainment of strong spin-photon coupling, is organized in three experimental WPs and guided by theoretical work. These WPs cover a sequence of logical steps needed to reach the project goals.
