摘要

我们提出并描述了基于集成的量子令牌协议的高级攻击,该协议允许实现不可克隆的量子硬币。相同准备的量子比特集合的多个初始化不同的令牌被组合成一个量子硬币,可以由银行发行。一个复杂的复制令牌的尝试可以假设可以对子集成进行测量,甚至可以测量单个量子位。尽管这种高级攻击在技术上可能被认为是不可行的,但我们在这些条件下证明了协议的安全性。我们对不同类型的高级攻击进行了数值模拟,并通过IBM量子平台上的实验验证了我们的结果。最后,我们证明了量子币的安全性可以通过增加令牌的数量来提高。本文结合提供的数值模拟工具,根据IBM量子平台的实验数据进行验证,允许在任意量子系统中安全地实现我们基于集成的量子令牌协议。

Security analysis of ensemble-based quantum token protocol under advanced attacks
We present and characterize advanced attacks on an ensemble-based quantum token protocol that allows for implementing non-clonable quantum coins. Multiple differently initialized tokens of identically prepared qubit ensembles are combined to a quantum coin that can be issued by a bank. A sophisticated attempt to copy tokens can assume that measurements on sub-ensembles can be carried through and that even individual qubits can be measured. Even though such an advanced attack might be perceived as technically unfeasible, we prove the security of the protocol under these conditions. We performed numerical simulations and verified our results by experiments on the IBM quantum platforms for different types of advanced attacks. Finally, we demonstrate that the security of the quantum coin can be made high by increasing the number of tokens. This paper in conjunction with provided numerical simulation tools verified against experimental data from the IBM quantum platforms allows for securely implementing our ensemble-based quantum token protocol with arbitrary quantum systems.

期刊介绍: Driven by advances in technology and experimental capability, the last decade has seen the emergence of quantum technology: a new praxis for controlling the quantum world. It is now possible to engineer complex, multi-component systems that merge the once distinct fields of quantum optics and condensed matter physics. Quantum Science and Technology is a new multidisciplinary, electronic-only journal, devoted to publishing research of the highest quality and impact covering theoretical and experimental advances in the fundamental science and application of all quantum-enabled technologies.
