Origin Quantum Superconducting processor routes qubits coherently

Researchers affiliated with institutions in China, in collaboration with Origin Quantum, have demonstrated coherent quantum routers, essential components for a novel quantum random access memory system on a superconducting processor. The quantum router at the core of their implementation utilizes a transition composite gate scheme, preserving straightforward initialization while reducing circuit complexity; experiments achieved an average fidelity of 94.8% across three individual routers. A two-layer quantum routing network achieved a fidelity of 82.4%. These results represent an advancement in quantum routing technology, providing…
