Quantum Market Entanglement
Quantum-correlated valuation methodology for stabilizing financial markets through entangled neural traders — replacing speculative collapse dynamics with quantum-stabilized equilibria.
Core Paper
Entangled Neural Traders (arXiv: 2602.06367)
Quantum stock market prototype where entanglement between traders' valuations mitigates runaway devaluation in speculative busts. Key results:
- RL agents with quantum-correlated qubit-encoded valuations stabilize prices
- Quantum agents achieve higher net worth than classical counterparts
- Quantized p-guessing game shows entanglement eliminates pathological Nash equilibrium
- Quantum correlations serve as novel endogenous mechanism for market stabilization
Usage Patterns
Pattern 1: Quantum Market Model
Build quantum market simulation:
- Encode trader valuations as qubit states
- Introduce entanglement between trader pairs
- Use RL agents to learn trading strategies
- Observe price stabilization effects
# Conceptual framework
# Trader valuation: |v⟩ = α|0⟩ + β|1⟩
# Entangled pair: |Φ⟩ = (|00⟩ + |11⟩)/√2
# Effect: Correlated valuations prevent runaway devaluation
Pattern 2: Quantized p-Guessing Game
Model speculative behavior:
- Define classical p-guessing game with pathological Nash equilibrium
- Quantize the game using qubit strategies
- Show entanglement eliminates the pathological equilibrium
- Demonstrate convergence to stable pricing
Pattern 3: Market Stabilization Analysis
Compare quantum vs classical market dynamics:
- Measure price volatility in classical market (high in speculative busts)
- Measure price volatility in quantum-entangled market (stabilized)
- Compare trader net worth (quantum > classical)
- Identify entanglement as endogenous stabilizer
Mathematical Framework
Qubit-Encoded Valuation
Trader i's valuation encoded as qubit state: |vᵢ⟩ = cos(θᵢ/2)|0⟩ + e^(iφᵢ)sin(θᵢ/2)|1⟩
Entangled Valuation Pairs
Entanglement creates correlated valuation structure: |Φ⁺⟩ = (|00⟩ + |11⟩)/√2
This correlation prevents independent speculative overvaluation.
Stabilization Mechanism
Entanglement → correlated beliefs → coordinated pricing → eliminated pathological equilibrium
Error Handling
Classical Market Collapse
- Symptom: Runaway devaluation in speculative bust
- Quantum fix: Entanglement between traders coordinates expectations
- Verification: Compare Nash equilibria with/without entanglement
Implementation Scale
- Current: Single-commodity prototype
- Extension needed: Multi-asset markets, realistic order books
