Welcome to the Quantum News Daily Brief. Story 1: Peking University Team Develops Bias-Corrected Moment Estimator for Quantum Metrology. Shaowei Du of the Peking University and colleagues from Shenzhen Technology University, INO-CNR, and Shanxi University have made a key advance in quantum metrology by constructing a bias-corrected estimator with bias scaling as O(1/ν³), where ν represents the number of measurements. This allows determination of how many measurements are needed to operationally
