  "textContent": "Chinese scientists developed a quantum dot device that emits photon pairs with 98.3 percent purity and 29.9 percent generation efficiency under pulsed excitation. The research, published in Nature Materials, sets a new benchmark in quantum optics for reliable two-photon sources. The result advances the global pursuit of photonic technologies for encryption, medical imaging, and precision […]",
