The main objective of this paper is to improve the communication costs in distributed quantum circuits. To this end, we present a method for generating distributed quantum circuits from monolithic quantum circuits in such a way that communication between partitions of a distributed quantum circuit is minimized. Thus, the communication between distributed components is performed at a lower cost. Compared to existing works, our approach can effectively map a quantum circuit into an appropriate number of distributed components. Since teleportation is usually the protocol used to connect components in a distributed quantum circuit, our approach ultimately reduces the number of teleportations. The results of applying our approach to the benchmark quantum circuits determine its effectiveness and show that partitioning is a necessary step in constructing distributed quantum circuit.

优化的量子电路分区

本文的主要目标是提高分布式量子电路中的通信成本。为此，我们提出了一种从单片量子电路生成分布式量子电路的方法，以最小化分布式量子电路分区之间的通信。因此，分布式组件之间的通信以较低的成本进行。与现有工作相比，我们的方法可以有效地将量子电路映射到适当数量的分布式组件中。由于隐形传态通常是用于连接分布式量子电路中组件的协议，因此我们的方法最终会减少隐形传态的数量。
