  We schedule the Steane [[7,1,3]] error correction on a model ion trap
architecture with ballistic transport. We compare the level one error rates for
syndrome extraction using the Shor method of ancilla prepared in verified cat
states to the DiVincenzo-Aliferis method without verification. The study
examines how the quantum error correction circuit latency and error vary with
the number of available ancilla and the choice of protocol for ancilla
preparation and measurement. We find that with few exceptions the
DiVincenzo-Aliferis method without cat state verification outperforms the
standard Shor method. We also find that additional ancilla always reduces the
latency but does not significantly change the error due to the high memory
fidelity.
