The simulations presented thus far have considered the absolute quantum state of the system at the end of the relevant process normalised relative to the initial state . It is not possible to normalise the experimentally determined quantum state in this way as the initial state is not determined. Instead, the fitted state was normalised by the magnitude of the calculated expectation values, and so is insensitive to an overall loss in magnetisation. This relative normalisation process can dramatically increase the experimental fidelity, especially for the simulations of the entangling gate considering anisotropic coupling frequencies. The uniformly and orientationally weighted simulations with 𝜔 C = 2 MHz have simulated pseudofidelities of just 0.746 and 0.820, but normalised pseudo-fidelities of 0.963 and 0.927.
