常见问题
关于免费入门量子计算的快速解答。
量子计算真的可以免费入门吗？
可以。你可以使用本地模拟器（Qiskit Aer、Cirq、PennyLane、NVIDIA CUDA-Q）零成本运行量子电路，并通过免费的云端额度访问真实的量子处理器，例如 IBM Quantum 的 Open Plan 每月提供免费的 QPU 时间。学习和构建无需购买硬件或付费订阅。
运行我的第一个量子程序最简单的方法是什么？
用 pip 安装量子 SDK（例如 pip install qiskit），或使用 HLQuantum 提供统一的高层 API。你可以在自己的笔记本电脑上几分钟内构建并模拟一个 Bell 态或 Grover 搜索，准备好后再把同一个电路提交到真实的 QPU。
我需要购买量子计算机或 GPU 吗？
不需要。模拟器在普通 CPU 上即可运行，使用 NVIDIA CUDA-Q 的 GPU 加速模拟是可选的，且本地同样免费。真实的量子硬件通过免费的云端计划远程访问——你无需拥有或托管 QPU。
初学者应该从哪个量子 SDK 开始？
IBM Qiskit 拥有最大的社区并可免费访问真实硬件，是最常见的入门选择。PennyLane 非常适合量子机器学习。HLQuantum 位于它们之上，让你只需编写一次电路，即可在 Qiskit、Cirq、PennyLane、Braket、CUDA-Q 或 IonQ 上运行，而无需修改代码。
