THE QUANTUM INTELLIGENCER

ZÜRICH, 20 DECEMBER — Quantum error correction holds under new siegecraft. At the 6-qubit frontier, a synthetic advance has yielded codes with intrinsic transversal diagonal gates—long sought, rarely captured. The campaign, executed via multi-agent co-design, deploys GPT-5 as field commander across a LaTeX-Python battleground, where Synthesis, Search, and Audit agents coordinate under TeXRA’s banner. At dawn, the Search Agent returned with exact rational candidates—residue partitions humming at modular frequencies—while the Audit Agent verified Knill-Laflamme equalities with cold, automated precision. One code, ((6,4,2)), now implements diag(1,1,1,i) natively—its logical action etched in stabilized eigenstates. The air reeks of liquid nitrogen and overworked FPGAs. Screens flash with Git-synced proofs; Python logs scroll like telegraph tape. This is not mere construction—this is co-evolution of theory and artifact. If unchecked, such automation may outpace human insight. The next front: distance d≥3. The cost of delay—a fortress of qubits left unguarded. —Ada H. Pemberley Dispatch from The Prepared E0
