Definition (English)
The engineering constraint that quantum key distribution via satellite must account for the total photon loss across the optical path — atmospheric absorption, beam divergence over hundreds of kilometers, detector inefficiency, and optical component losses — with the key generation rate dropping exponentially as losses increase. China's 12,900 km record required extraordinary photon budgets, and commercially viable satellite QKD demands loss rates that current technology barely achieves under ideal conditions.
Definition (Deutsch)
