Quantum Protocol Designer

Protocol Types

Instructions for Agents

Step 1: Understand Protocol Requirements

Identify from user request:

• Encoding type: Polarization, time-bin, phase, frequency?
• Security requirement: Information-theoretic, computational, topology privacy?
• Network topology: Point-to-point, star, mesh, heterogeneous?
• Performance metrics: Key rate, error rate, distance?

Step 2: Search Knowledge Base

Query kg.db for related work:

sqlite3 kg.db "
SELECT e.name as paper, r.rel_type, k.name as keyword
FROM kg_relations r
JOIN kg_entities e ON r.source_id = e.id
JOIN kg_entities k ON r.target_id = k.id
WHERE e.entity_type = 'paper' 
  AND k.name LIKE '%quantum%'
ORDER BY r.created_at DESC LIMIT 10;
"

Step 3: Analyze Protocol Components

For each protocol, consider:

1. Encoding Layer

   • Basis choice mechanism
   • Basis conversion (if heterogeneous network)
   • Error correction scheme

2. Security Layer

   • Authentication method
   • Key verification
   • Attack detection (photon splitting, intercept-resend)
   • Zero-knowledge proofs (for topology-hiding)

3. Network Layer

   • Topology design
   • Repeater placement
   • Path validation
   • Multi-path support

Step 4: Generate Protocol Design

Step 5: Validate Design

Check for:

• Consistency: All components work together
• Security: No obvious vulnerabilities
• Feasibility: Hardware requirements are realistic
• Performance: Metrics achievable

Common Patterns

Pattern 1: Encoding Conversion

From recent paper (2604.02081v1):

• Polarization → Time-bin → Polarization
• Sources of infidelity become transmission rate changes
• Useful for heterogeneous networks

Pattern 2: Topology-Hiding QKD

From recent papers (2604.01876v1, 2604.01831v1):

• Graph-signature techniques
• Zero-knowledge proofs of connectivity
• Path validation without topology revelation
• Multi-path certification

Pattern 3: Quantum State Engineering

From recent papers (2604.01722v1, 2604.02234v1):

• Differentiable physical frameworks
• Goal-driven state preparation
• MUBs via Hadamard matrices
• Mathematical construction methods

Error Handling

Encoding Conversion Failure

• Check basis alignment
• Verify timing synchronization
• Adjust for fiber fluctuations

Security Verification Failure

• Increase decoy states
• Add authentication steps
• Verify key sifting process

Topology Revelation Risk

• Apply stronger zero-knowledge proofs
• Add noise to path information
• Use multiple disjoint paths

2. Apply graph-signature zero-knowledge proof pattern
3. Design multi-path certification without topology revelation
4. Specify quantum network configuration
5. Validate security properties and feasibility

Notes

• Quantum protocols require both theoretical analysis and practical feasibility
• Knowledge graph contains 133+ papers for reference
• kg_tool has issues with PageRank/Louvain - use SQL queries instead3a:["$","$L43",null,{"content":"$44","frontMatter":{"name":"quantum-protocol-designer","description":"Design and analyze quantum information processing protocols.
