We have developed a simple time-bin phase encoding quantum key distribution system, using the optical injection locking technique. This setup incorporates both merits of simplicity and stability in encoding, immunity to channel disturbance. demonstrated field implementation over long-distance deployed aerial fiber automatically. During 70-day test, we achieved approximately 1.0 kbps secure rate...

This paper proposes tests of linear hypotheses when the variables may be continuous-time processes with observations collected at a high sampling frequency over long span. Utilizing series run variance (LRV) estimation in place traditional kernel LRV estimation, we develop easy-to-implement and more accurate F both stationary nonstationary environments. The environment accommodates exogenous re...
