QFS (Quantum Financial System) is regarded as a "savior" of future finance, but it lacks empirical support. While its theory requires extensive collaboration and investment, in reality, central banks worldwide are advancing Digital Currency (CBDC) projects, demonstrating efforts toward digitalization and decentralization. Financial institutions are exploring applications of quantum technology and blockchain, reshaping the financial ecosystem. Although QFS may be difficult to realize, the future will still face accelerated development of financial innovation.
