516.4 ms (jones) / 365.4 ms (transport) · 3.8 ions per transport instruction · not buildable · up to 2 waveforms a cycle, no select bits, shims 0.2 ms at 1:1 / 3.7 ms at 1:16 · R10: Lean checker + tableau
a periodic lattice, every row and column a closed loop, with one ancilla per check pair: 516.4 ms at 3.79 ions per instruction, against the planar grid's 648.1 at 72 ancillas (22) and 869.9 at 24 (23). The wrap is worth 1.25x, the ancillas 1.34x. It runs under the one-waveform model (control.model simd_classes: one motion a cycle, the R22 split) on direct wiring, so its time is an upper bound for a direct machine. The study's 97 ms was this programme before the R22 split, several motions a cycle.
