Quantum financing system: A survey on quantum algorithms, potential scenarios and open research issues

Quantum financing system is a foreseeable future of finance, which will demonstrate more agile, accurate, and secured performance. Financial markets and related activities are changing dynamically, and quantum computing is one of the emerging technologies responding to financial developments. We attempt to outline a theoretical framework to illustrate a quantum financing system, including quantum financing algorithms, quantum financing circuits, and potential financial scenarios. Since quantum computer is still in the early stage, challenges and future directions are also discussed from a technological and operational perspective. This study provides a resource for researchers, practitioners and policymakers interested in empowering quantum computing to revolutionize financial services and systems. The research is one of the foundational studies that describe future ecology of quantum financing system.
