Quantum Reinforcement Learning Matches Classical Portfolio Performance

An arXiv paper by Vincent Gurgul (submitted Jan. 20, 2026) presents a quantum reinforcement learning (QRL) approach using variational quantum circuits for dynamic portfolio optimization. The study shows quantum agents match or sometimes exceed classical deep RL's risk-adjusted returns on real financial data while using far fewer parameters, and notes practical cloud deployment latency currently limits end-to-end runtime. Code is released open-source.
