Cheng Li is shown with the outdoor experimental setup. The sunlight concentration module, including the Fresnel lens and the solar concentrator, is mounted on a solar-tracking motor to ensure stable power delivery. The entanglement generation and detection setup, including the nonlinear crystal and the single-photon detectors, are shielded in an optical enclosure placed inside a blackout tent.
