摘要：
数字货币是以数字形式存在的货币。在该模型中，维持货币供应量的完整性是核心关切，因此防止双重支付往往是安全数字货币方案的核心。量子货币利用量子力学的不可克隆原理，实现一种对双重支付免疫的货币。该方案面临的挑战之一是用户需要目前尚难以获得的技术。在此，我们提出一种量子货币模型，通过将量子存储和处理委托给一个我们称之为“量子金库”的中介，从而减轻对量子钱包的需求。我们开发了这种量子赋能数字货币的基本构建模块，并讨论了其优势与挑战。
英文摘要：
A digital currency is money in a digital form. In this model, maintaining integrity of the supply is a core concern, therefore protections against double-spending are often at the heart of a secure digital money scheme. Quantum money exploits the quantum mechanical principle of no-cloning to enable a currency that is immune to double spending. One of the challenges of the scheme is that users require technology that is currently out of reach. Here, we propose a model for quantum currency, which alleviates the need for quantum wallets by delegating quantum storage and processing to an intermediary that we call a "quantum vault". We develop the basic building blocks of this quantum-enabled digital currency and discuss its benefits and challenges.
