Analysis skill for detecting and mitigating barren plateaus in variational circuits

General

What this skill does


# Barren Plateau Analyzer

## Purpose

Provides expert guidance on analyzing and mitigating barren plateaus in variational quantum circuits, ensuring trainability of quantum machine learning models.

## Capabilities

- Gradient variance estimation
- Cost function landscape analysis
- Expressibility vs. trainability tradeoff
- Initialization strategy evaluation
- Local cost function design
- Layer-wise training strategies
- Entanglement-induced BP detection
- Noise-induced BP analysis

## Usage Guidelines

1. **Variance Estimation**: Sample gradient variance across parameter space
2. **Scaling Analysis**: Evaluate gradient scaling with qubit number
3. **Architecture Modification**: Redesign circuits to avoid BP regions
4. **Initialization**: Use structured initialization to avoid plateaus
5. **Training Strategy**: Apply layer-wise or identity-initialized training

## Tools/Libraries

- PennyLane
- Qiskit
- JAX
- NumPy
- Matplotlib

Included

Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.
