What is Applied Quantum Computing ?
Today’s quantum processors with just 50-100 qubits are performing practical tasks like modeling chemical reactions. This could lead to faster drug discovery and materials design. Quantum machine learning can spot subtle patterns in data to improve decision-making for health care, finance and more. Powerful quantum simulations may someday design novel proteins or perfectly optimize huge systems like power grids.
How Applied Quantum Computing Differs ?
Applied quantum computing differs from traditional quantum computing in its
focus on practical applications. Rather than exploring theoretical possibilities, applied quantum computing aims to develop tangible solutions for real-world challenges. This shift in focus has brought quantum computing from the realm of theory into the realm of practicality.
