Researchers have developed a new spin-photon interface that operates in the telecommunications C-band, crucial for long-distance quantum information transmission. The advance is based on InGaAs/GaAs quantum dots, achieving a hole spin dephasing time of 20 ns at 4 K. This result is significant because the C-band (1530-1565 nm) is the region of lowest attenuation in silica optical fibers, making it ideal for distributed quantum networks.
