论文摘要
我们说明了量子计算技术在调查一个简单系统的热力学特性中的应用，该系统由三个量子旋转组成，具有沮丧的对相互作用，并在经典计算方案中处理时受硬符号问题的影响。我们展示了量子算法如何完全解决问题，并讨论如何应用于更复杂的身体感兴趣系统，重点是可能的系统学及其控制。
We illustrate the application of Quantum Computing techniques to the investigation of the thermodynamical properties of a simple system, made up of three quantum spins with frustrated pair interactions and affected by a hard sign problem when treated within classical computational schemes. We show how quantum algorithms completely solve the problem, and discuss how this can apply to more complex systems of physical interest, with emphasis on the possible systematics and on their control.
