TCS Unveils Hybrid Quantum-Classical Method for Portfolio Optimization

10/23/2025

Summary

Story summary

Tata Consultancy Services (TCS) introduced a method for solving QUBO problems by merging classical computation with neutral atom quantum computing and partitioning problems into subproblems using Analog Hamiltonian Simulation.
The framework was tested on a 50-asset portfolio optimization problem and showed better performance than classical methods.
Findings show the promise of hybrid quantum-classical algorithms and the importance of problem decomposition for scalability; future work will refine techniques for broader applications.
