•Researchers from National Tsing Hua University and collaborators have achieved device-independent quantum steering certification using Gaussian protocols.
•This breakthrough allows quantum correlation (steering) to be verified in complex networks where most devices are untrusted, a significant shift from previous limitations.
•The method uses continuous variables and 'fiduciary states' for calibration, paving the way for applications like secure random number generation and more scalable quantum networks.
