NSN Integration with LIMIT-Graph and REPAIR

Comprehensive integration of Nested Subspace Networks (NSNs) with LIMIT-Graph and REPAIR to enhance quantum benchmarking and multilingual edit reliability.

Overview

This integration implements three key stages:

1. Backend-Aware Rank Selection: Dynamically adjust model rank based on quantum backend constraints
2. Multilingual Edit Reliability: Evaluate how rank affects correction accuracy across languages
3. Contributor Challenges: Design leaderboard tasks with rank-aware evaluation and compute-performance frontiers

Stage 1: Backend-Aware Rank Selection

Features

• Dynamic Rank Adjustment: Automatically select optimal NSN rank based on quantum backend characteristics
• Backend Support:
  • IBM Manila (5 qubits, noisy) → Low-rank inference (r=8)
  • IBM Washington (127 qubits, high-fidelity) → High-rank inference (r=128-256)
  • Russian Simulators (stable) → Maximum-rank inference (r=256)
• FLOPs vs Reliability Visualization: Plot compute-performance curves for each backend

Usage

from quantum_integration.nsn_integration import BackendAwareRankSelector, BackendType

# Create selector
selector = BackendAwareRankSelector()

# Get rank recommendation
recommendation = selector.get_rank_recommendation(
    backend_type=BackendType.IBM_WASHINGTON,
    compute_budget=1e8,

)

print(f"Recommended Rank: {recommendation['recommended_rank']}")
print(f"Expected Reliability: {recommendation['expected_reliability']:.3f}")
print(f"Rationale: {recommendation['rationale']}")

# Compute FLOPs vs reliability curve

)

print(f"Accuracy: {result.edit_accuracy:.3f}")
print(f"Uncertainty: {result.uncertainty:.3f}")

# Comprehensive analysis
languages = ['english', 'chinese', 'indonesian', 'swahili']
analysis = evaluator.analyze_rank_language_matrix(languages)

# Get uncertainty weights for balanced training
weights = evaluator.compute_uncertainty_weights(languages)

Key Concepts

Nested Subspace Networks (NSNs)

NSNs represent model parameters in nested subspaces of increasing rank:

• Low Rank (r=8-16): Fast inference, lower accuracy, suitable for noisy backends
• Medium Rank (r=32-64): Balanced performance
• High Rank (r=128-256): Maximum accuracy, high compute, requires stable backends

Backend-Aware Selection

Quantum backend characteristics determine optimal rank:

• Qubit Count: More qubits → higher rank capacity
• Error Rate: Lower error → higher rank feasibility
• Gate Fidelity: Higher fidelity → better high-rank performance
• Coherence Time: Longer coherence → supports complex circuits

Multilingual Subspace Containment

Low-resource language edits often nest within high-resource language subspaces:

• Indonesian → English: ~85% containment at rank 128
• Swahili → English: ~80% containment at rank 128
• Vietnamese → Chinese: ~75% containment at rank 64

This enables transfer learning and cross-lingual edit propagation.

Integration with Existing Components

REPAIR Integration

from quantum_integration.social_science_extensions import REPAIRInferenceWrapper
from quantum_integration.nsn_integration import BackendAwareRankSelector

# Select rank based on backend
selector = BackendAwareRankSelector()
rank_config = selector.select_rank(BackendType.IBM_WASHINGTON)

# Use rank in REPAIR inference
# (REPAIR wrapper can be extended to accept rank parameter)

Quantum Health Monitoring

from quantum_integration import quantum_health_checker
from quantum_integration.nsn_integration import BackendAwareRankSelector

# Check backend health
health = quantum_health_checker.check_backend_health('ibm_washington')

# Adjust rank based on health
if health['status'] == 'degraded':
    # Use lower rank for stability
    rank = 32
else:
    # Use optimal rank
    rank = selector.select_rank(BackendType.IBM_WASHINGTON).rank
