Non-Maximally Entangled States for Quantum Key Distribution in Underwater Channels: BBM92 Protocol via Kraus Operators
Derives closed-form QBER and SKR expressions for BBM92 QKD using non-maximally entangled states in underwater channels modeled by amplitude-damping plus depolarizing Kraus operators, validated by Monte Carlo simulations across clear ocean, coastal, and turbid water.
