• •**Understand physical T₁ relaxation** and its amplitude damping model
• •**Compute channel fidelity and error rates** for each noise model
• •**Connect noise parameters to physical quantities** (T₁, gate times)
• •**Visualize Bloch sphere contraction** under noise
• •**Apply these channels in quantum error correction design**
