In this article we present the transfer of NMR quantum computing methods to EPR, using a bis-nitroxide model system (Compound 1, Figure , synthesis and characterisation in SI) to demonstrate the pseudo-entanglement and subsequent tomography of two weakly coupled electron spins. The fidelity of the entangling gate and state determination are critically assessed, through which we determine the primary causes of error accumulation and discuss these in terms of the feasibility of using MESQs as multi-qubit gates.
