In this work we present a publicly verifiable quantum money protocol which assumes close to no quantum computational capabilities. We rely on one-time memories which in turn can be built from quantum conjugate coding and hardware-based assumptions. Specifically, our scheme allows for a limited number of verifications and also allows for quantum tokens for digital signatures. Double spending is prevented by the no-cloning principle of conjugate coding states. An implementation of the concepts presented in this work can be found at https://github.com/neverlocal/otm_billz.

翻译：本文提出了一种公开可验证的量子货币协议，该协议几乎不依赖量子计算能力。我们基于一次性存储器构建该协议，而一次性存储器可通过量子共轭编码与硬件假设实现。具体而言，本方案支持有限次数的验证，并可生成用于数字签名的量子令牌。通过共轭编码态的不可克隆原理防止双重支付。本工作所述概念的实现代码可见于 https://github.com/neverlocal/otm_billz。
