# Quantum Perspective on Digital Money: Towards a Quantum-Powered Financial System
## 8 Conclusions  
Quantum money offers an exciting vision for the future of digital currency, with security features grounded in quantum mechanics that surpass classical capabilities. By relying on the no-cloning theorem, quantum teleportation, and entanglement distribution, quantum money could transform financial systems, enhancing both security and decentralization. While some aspects of quantum money have already been discussed [8; 9; 10; 11], the present perspective provides new insights into the practical implementation of quantum wallets, the potential impact of quantum money on the financial system (including a comparison with CBDCs), and its integration within emerging concepts of the Quantum Internet. Moreover, we showcase key features of quantum money by performing a SWOT analysis, which highlights not only its positive aspects but also the challenges associated with this concept. Realizing the potential of quantum money will require overcoming technical, infrastructural, and regulatory challenges. In addition, one might expect social reluctance to adopt quantum money. Already it can be seen that the widespread use of digital currency prompts some people to defend the right to use cash. However, with ongoing advancements in quantum technology, especially in the Quantum Internet, quantum money may one day become a practical and highly secure form of currency, integrated with currently developing networks for quantum communication and computation. The use of quantum teleportation for transferring quantum money promises a secure, efficient, and decentralized alternative to conventional banking transactions. With continued advancements in quantum infrastructure and the integration of quantum blockchains, a quantum financial system could redefine global finance, benefiting from the fundamental principles of quantum mechanics for enhanced security and real-time transfers. Moreover, since quantum money is intrinsically tied to specific physical particles used to encode quantum states, its creation will be restricted to authorized institutions capable of generating certified states. This will inevitably limit the widespread money creation by commercial banks, helping to reduce inflation and better preserve the value of savings. The concept of quantum money is further enriched by advances in quantum communication and network infrastructure. The advent of the Quantum Internet and quantum-secure networks offers a framework for storing, validating, and transferring quantum money over long distances, potentially reshaping the financial landscape. By integrating quantum money with these emerging infrastructures, it may be possible to create a decentralized, highly secure financial system. Furthermore, combining quantum money with quantum blockchain technology could lead to a new form of ledger that not only records \begin{table}

Since entanglement-based quantum technologies are transitioning from laboratories to real-world applications, we can expect that transferring quantum money will someday be just an additional use case for QINs.
