Tiny metal circuits cooled near absolute zero act as qubits; microwave pulses flip and entangle them, and couplers turn links between neighbours on and off.
Tianyan-P2000 sends photons through a large web of optical paths at room temperature and counts where they land, a task classical computers struggle to mimic.
The Cqlib toolkit maps a program onto the chosen chip's wiring; classical servers dispatch the circuits, gather the samples and process the results.

Tianyan quantum cloud, quantum-secure calls
China Telecom's quantum subsidiary, set up in Hefei in 2023 with 3 billion yuan of capital. It runs Tianyan, China's main public quantum-computing cloud, and sells quantum-secured communication services.
