HEIDELBERG — Qubits trembling on the edge of collapse. Now, a new protocol slashes the overhead: single-shot error correction, universal gates, no magic distillation. Code-switching between 2D/3D HGP codes holds the line. Fault-tolerance in one stroke. The lattice has shifted.
HEIDELBERG, 28 DECEMBER —
Qubits flicker like candle flames in a storm. The noise is ceaseless. For years, the line stalled at magic state distillation—bloated, slow, costly. Now, a breakthrough: code-switching between 2D hypergraph product codes and high-rate 3D variants. A single measurement round suffices. Error correction. State prep. Universal gates. All achieved in constant depth.
I stood in the lab as the first logical CCZ gate fired—no preparatory distillation, no cascading corrections. Just silence, then success. The air hummed with 3D lattices stitched through hyperedges, expanders woven like fortress walls.
This is single-shot universality. Fault-tolerance under both adversarial and stochastic noise. A path cleared through the overhead wilderness. Halt not. The quantum frontier advances.
