According to the Global Times citing a report in Science and Technology Today, Chinese research teams have achieved a breakthrough on an independently developed superconducting quantum computer, with tests showing information transmission efficiency of up to 98 percent for a single quantum router.
Several Chinese research teams developed a coherent quantum routing system for bucket-brigade quantum random access memory (QRAM) on the Origin Wukong superconducting quantum computer. The system acts like a “fast lane” for data transmission, helping address a key challenge in scaling up QRAM. They built three independent quantum routers and a two-layer quantum routing network on China’s third-generation independent superconducting quantum computer Origin Wukong for testing. The results showed that a single quantum router achieved an information transmission efficiency of up to 98 percent, while the two-layer network reached an overall transmission efficiency of 93 percent. In random-access tests, the average fidelity reached 94.8 percent for the single quantum router and 82.4 percent for the two-layer network.
According to the researchers, the breakthrough offers a new way to build scalable QRAM on existing superconducting hardware. The approach could help cut computing costs and improve efficiency.
