Concepts and conventions¶
Use this index to check what a quantity or setting means. Each row identifies the main explanation and a runnable lesson. For a specific operation, use the task guides.
| Concept | Main explanation | Runnable lesson |
|---|---|---|
| Units, signs and state encoding | Physical conventions | Units and a π pulse |
| String positions and logical qubits | Bit order | Asymmetric measurement |
| Probabilities, counts and observables | Sampling and expectations | Finite sampling |
| State passed between Digital and Analog blocks | Shared simulation state | A D-A-D experiment |
| State representation and time integration | Simulation methods and precision | Resource checks |
| Physical, numerical and statistical differences | Error sources | Noise and precision comparisons |
| Target specifications and execution support | Target capabilities | Target checks and discretization |
| Experimental settings, data and analysis | Reproducibility | Repeated experiments |
See the glossary for Chinese and English terms. These explanations describe current SDK behavior; the linked lessons develop the assumptions behind equations and numerical references.
