Circuit Depth Limit:
Mapping: Noise → Decoherence → Error Rate → QEC Breakdown
🔵 Blue Curve = Error Rate growth (decoherence-driven)
🟡 Yellow Dot = Current system state
🔴 Red Line = Fault-tolerance threshold (~1%)
↑ High region = Classical collapse regime
→ Mid region = Limited quantum advantage
↓ Low region = Stable quantum computation
