Hybrid Financial Systems and the Role of Quantum Computing in Modern Finance
Amy Kwalwasser Amy Kwalwasser is a New York City-based quantum computing specialist focused on the application of quantum algorithms in quantitative finance. Hybrid financial systems represent a pragmatic shift in how advanced computation is applied to modern finance. Rather than waiting for fully mature quantum computers to replace classical infrastructure, the current direction is integration: embedding quantum processing as a specialized layer within existing financial workflows. This approach reflects both the limitations of current quantum hardware and the increasing computational demands of global financial markets. At a high level, a hybrid financial system divides computational responsibilities between classical and quantum resources. Classical systems continue to handle core functions such as data ingestion, deterministic processing, execution pipelines, and real-time trading infrastructure. These systems are optimized, stable, and capable of operating at the scale required b...
