This results in entangling the spatial and spin parts of a two-component Pauli wavefunction such that the entailed coherence can be conveniently certified by spin measurements alone. The implementability of this scheme is analysed using NV-centre nanodiamonds of masses $\sim 10^{10}$ amu based on the current technological capabilities.
