(a) The operational infidelity associated with the adiabatic sequential swap for N=18. The simulations account for the JT orientation of nitrogen impurities and utilize the optimized adiabatic ramp profile42. Simulations utilize an optimized coupling strength of 8.71 kHz (18.1 nm spacing). Full numerical integration of the time-dependent Schrödinger equation produces infidelity contour plots as a function of total swap time and 
. (b) Numerical simulations of the operational infidelity associated with FFST for N=7. Non-nearest neighbour interactions are assumed to be refocused through dynamic decoupling as described in the Methods. Simulations, which utilize an optimized coupling strength of 12.6kHz (16 nm spacing), are based on a full diagonalization and also account for the JT orientation of nitrogen impurities. Infidelity contour plots are again shown as a function of total swap time and
