# Chinese teams test two-layer quantum-routing network on Origin Wukong

_Thursday, September 3, 2026 at 8:00 AM EDT · Science · Latest · Tier 2 — Notable_

Several Chinese research teams tested a coherent routing system for bucket-brigade quantum random access memory on the Origin Wukong superconducting quantum computer. The tests used three independent quantum routers and a two-layer routing network. The source reports transmission efficiency of up to 98% for a single router and 93% across the two-layer network; random-access fidelity averaged 94.8% and 82.4%, respectively. Researchers said the work offers an approach to scalable QRAM on existing superconducting hardware.
