測試它
正在使用「qiskit」。 Create a quantum circuit that creates a Bell state and run it on a local simulator
預期結果:
- Created 2-qubit quantum circuit with Hadamard and CNOT gates
- Applied H(0) for superposition then CX(0,1) for entanglement
- Added measurements to both qubits
- Ran with StatevectorSampler: 1024 shots
- Results: {'00': ~512, '11': ~512} - perfect entanglement confirmed
正在使用「qiskit」。 How do I set up my IBM Quantum account and run on real hardware
預期結果:
- Install Qiskit: uv pip install qiskit
- Create IBM Quantum account at quantum.ibm.com
- Save your API token for authentication
- Use QiskitRuntimeService to connect to backends
- Check backend status and queue times before submitting

Pure documentation skill containing only markdown files with quantum computing references. No executable code, scripts, or network operations. Static findings are false positives caused by markdown code formatting (backticks) being misidentified as shell commands, and quantum algorithm names (VQE, QAOA, Grover) being misidentified as weak cryptographic algorithms.

你能建構什麼
量子化学模拟
使用VQE算法计算分子基态能量并模拟化学反应
优化算法
实现QAOA以解决MaxCut和投资组合优化等组合优化问题
量子机器学习
构建量子核函数和神经网络以完成分类和模式识别任务
試試這些提示
创建贝尔态
使用Qiskit创建一个纠缠两个量子比特并测量它们的贝尔态电路。展示如何在本地使用StatevectorSampler运行它。
运行VQE算法
展示如何使用变分量子本征求解器（VQE）用Qiskit找到H2分子的基态能量。
为硬件转换电路
编写代码将量子电路转换为IBM Quantum硬件格式，设置optimization_level=3并解释转换阶段。
使用QAOA解决MaxCut
使用Qiskit原语实现量子近似优化算法（QAOA）来解决4节点图上的MaxCut问题。
最佳實務
- 在昂贵的硬件后端上运行之前，先用本地模拟器测试电路
- 生产工作负载始终使用optimization_level=3进行电路转换
- 对VQE和QAOA等迭代算法使用会话模式以减少排队时间
避免
- 直接在硬件上运行未经转换且未优化的电路
- 为用例选择错误原语（Sampler vs Estimator）
- 在嘈杂的量子硬件上运行时跳过错误缓解
常見問題
Sampler和Estimator原语之间有什么区别？
Sampler返回测量比特串和概率。Estimator返回可观测量的期望值。Sampler用于优化/搜索，Estimator用于化学/物理。
在IBM Quantum上可以使用多少个量子比特？
IBM Quantum提供100多个量子比特系统。免费层提供对较小后端的访问。提交前检查backend.num_qubits和排队时间。
我可以离线运行此技能吗？
可以，本地模拟器（StatevectorSampler、AerSimulator）无需账户即可工作。访问硬件需要IBM Quantum账户和API令牌。
在量子硬件上运行我的数据安全吗？
IBM Quantum可能会出于质量目的保留作业数据。对敏感工作负载使用本地模拟器。审查IBM Quantum条款以满足合规需求。
为什么我的电路在转换后看起来不同？
转换会将电路重写为使用硬件原生门并遵守量子比特连接性。这会增加SWAP门并可能增加深度，但对于执行是必要的。
Qiskit与其他量子框架相比如何？
Qiskit提供83倍更快的转换和比替代方案少29%的双量子比特门。它支持IBM Quantum、IonQ、Amazon Braket和本地模拟器。
