Build your first quantum experiment
The final project is one complete experiment. Write a number prediction for the Bell circuit. Run 1,000 shots. Check the counts against the expected random wobble. Change one gate and predict again. Then record the circuit, shot count, seed, counts and explanation, so someone else can repeat both the result and your reasoning.
Why care? Reading about quantum computing is not the same as doing it. Running this loop once, properly, is the difference.
Everything in this course fits into one loop:
- Predict: work out the perfect chances by hand, and write them down first.
- Build: write the circuit as Circuit IR in the Lab.
- Run: pick a number of shots and run it.
- Inspect: compare the counts with your prediction, including the expected random wobble.
- Modify: change exactly one thing, and predict again before you run.
- Explain and record: keep the circuit JSON, the shot count, the seed, the counts, and a short written explanation. The seed is the number that starts the random sampler. It makes a simulated run exactly repeatable.
Think of a science fair project. The poster is not the project. The notes that let someone else repeat it are. The saved bundle is the experiment. A histogram screenshot without the circuit, seed and reasoning is just a picture.
