Ancilla management for Steane code article posted on arXiv

As part of the ORAQL project in collaboration with the GTRI QIS group, we examined how the management of ancilla affects the time and fidelity of error correction. The results are now posted on the arXiv: Comparison of ancilla preparation and measurement procedures for the Steane [[7,1,3]] code on a model ion trap quantum computer, arXiv:1305.0349.
