We use this to enact a mid-circuit erasure check for a dual-rail cavity qubit, detecting the joint vacuum state of the two cavities without perturbing the single-photon manifold. This measurement allows us to convert the most-likely qubit error (single photon loss to the vacuum) into erasures, which dramatically ease the task of quantum error correction and lead to higher thresholds in the surface code.
In part 2 of this two-part talk, we benchmark the performance of this mid-circuit erasure check on a dual-rail qubit and demonstrate that it is both high-fidelity and has minimal back action on the code space.
