论文摘要
量子计算机比古典计算机具有更高的效率解决一些重要的工业和科学问题。尽管当前的大多数实现都集中在两级量子位上，但大多数硬件中使用的基本物理能够将概念扩展到多层逻辑 - 可以使用Qudits，从而有望使用较高的计算能力和较低的错误率。基于最新的物理成就的强烈理论支持和动机，这也要求使用为这些设备编译量子电路的方法和工具。为了启用有效的Qudit汇编，我们介绍了单Qudit系统的能量耦合图的概念，并提供了一种自适应算法，该算法利用此表示来汇编任意单位。这导致了对最先进的汇编计划的重大改进，此外，还提供了权衡最差成本和运行时间的选择。开发的编译器可通过github.com/cda-tum/qudit-compilation获得开源许可。
Quantum computers have the potential to solve some important industrial and scientific problems with greater efficiency than classical computers. While most current realizations focus on two-level qubits, the underlying physics used in most hardware is capable of extending the concepts to a multi-level logic - enabling the use of qudits, which promise higher computational power and lower error rates. Based on a strong theoretical backing and motivated by recent physical accomplishments, this also calls for methods and tools for compiling quantum circuits to those devices. To enable efficient qudit compilation, we introduce the concept of an energy coupling graph for single-qudit systems and provide an adaptive algorithm that leverages this representation for compiling arbitrary unitaries. This leads to significant improvements over the state-of-the-art compilation scheme and, additionally, provides an option to trade-off worst-case costs and run-time. The developed compiler is available via github.com/cda-tum/qudit-compilation under an open-source license.
