Recent studies of globally controlled structures have culminated in a theoretical demonstration that fault-tolerant quantum computation can be carried out on a one--dimensional chain with control over two global fields only. This required some patterns of classical states to localise operations, which were stabilised with the Zeno effect. However, it is impossible to achieve perfect stabilisation using this method, so error correction of these states is desirable, and is the focus this paper.

    GRAPE-optimized global drives compress Hadamard sequences from ~3000 ns to ~320 ns and raise fidelity under strong relaxation from ~0.64 to ~0.96 in a 15-qubit globally driven ladder.
