Noise Model Clinic

Inspect how simple depolarizing and measurement noise change counts without changing the ideal algorithm.

Investigation

Compare an ideal Bell circuit with noisy variants and identify which errors create which count patterns.

Learning evidence

A table linking noise assumptions to count changes and confidence limits.

Interactive check

Guided local calculation. Simulated results, not quantum hardware or a full circuit simulator.

Explanation

Even when the ideal state has 90% probability of 0, a 20% bit flip mixes the observed distribution.

Completion checks

  • Separates ideal circuit from noisy observation.
  • Mentions finite-shot uncertainty.
  • Does not infer hardware performance from a toy model.
