14.1 ms (jones) / 14.1 ms (transport) · 2.7 ions per transport instruction · not buildable · R10: Lean checker + tableau

24 legs on the wires of a 4 x 4 junction lattice, Ba-Sr crystals; compiled by the baseline C2LR router. LER per round 1.00e-06, 95% interval 1.8e-07 to 5.7e-06 (1 errors in 200,000 shots)

LER per round 1.00e-06 (95%: 1.77e-07 to 5.66e-06)

1 logical errors in 200,000 shots of 5 rounds, decoder pymatching, seed 20260928; noise model qccd-noise@1. The stim circuit below has 24 detectors and 9 qubits, one per ion. Highest n̄ at a two-qubit gate: 0.824; longest chain at a gate: 2.

Hover a row for the clauses of the noise model's text that book it; the noise model, clause by clause, and every term it uses on the Evaluation page. Red lines below are noise. Each block is one hardware instruction: click it to move the animation there; the block of the current step is highlighted as the program plays.
