A Quantum Financial System (QFS) is a hypothetical financial system that would use quantum computing technology and quantum cryptography through a blockchain to manage financial transactions and data. The QFS is a new technological development that promises to revolutionize how we interact with money, streamlining and democratizing wealth generation. Quantum banking could bring several advantages over traditional financial systems, such as increased security, faster transaction processing times, and more sophisticated risk management capabilities. One of the main advantages of QFS is that the data is immutable and cannot be manipulated by any malicious actor. This is because a QFS would issue a digital number for each currency (dollar, euro, etc.) in each bank account, and the physical (GPS) position of each of these currencies will be monitored in real-time. Only gold-backed currencies with a digital gold certificate would be able to participate in the transactions of a QFS. The QFS is still in the experimental stage and not yet fully implemented.
