QubitCast represents a breakthrough in long-range weather forecasting, using quantum physics principles on conventional computers to detect hidden patterns in Earth's climate data. Unlike traditional weather models limited to 10 days of forecasting, the system will predict extreme weather events weeks to six months in advance.

the quantum Bayes' rule is defined as the rule for updating quantum states using the principle of minimum change (maximizing fidelity), and is mathematically realized by the Petz recovery map in many situations
