"用户在设计量子线路时往往是根据自己的算法需求来进行设计，但是现阶段的量子芯片难以实现所有比特之间都有耦合。因此，在量子计算硬件上执行量子线路时，我们需要通过一定的算法来将量子算法中所用到的比特进行重新排列，或者引入一些 [SWAP](https://www.mindspore.cn/mindquantum/docs/zh-CN/r0.10/core/gates/mindquantum.core.gates.SWAPGate.html) 门，来将本来不能耦合的比特耦合起来。这也就是比特映射算法。\n",
"\n",
"在这篇教程中，我们将首先介绍构成量子芯片中的量子节点对象 [QubitNode](https://mindspore.cn/mindquantum/docs/zh-CN/r0.10/device/mindquantum.device.QubitNode.html#mindquantum.device.QubitNode) 和量子拓扑图对象 [QubitsTopology](https://mindspore.cn/mindquantum/docs/zh-CN/r0.10/device/mindquantum.device.QubitsTopology.html#mindquantum.device.QubitsTopology)，然后将介绍如何利用比特映射算法来实现量子线路的编译。\n",
