SMBC and Toshiba Develop Quantum-Driven Equity Indices for Diversified Portfolios

Sumitomo Mitsui Banking Corporation and Toshiba Corporation have jointly developed two new equity indices using Toshiba’s quantum-driven technologies.

The indices are the SMBC/TOSHIBA Quantum Driven Diversified Japan Equity Index and the SMBC/TOSHIBA Quantum Driven Diversified U.S. Equity Index. They are designed to create well-diversified equity portfolios by applying Toshiba’s Simulated Bifurcation Machine to large-scale combinatorial optimization problems.

The companies said the initiative is intended to offer investors enhanced risk diversification options in volatile markets. The announcement highlights an early application of quantum-driven optimization tools in financial index construction.

The development appears in May 28 coverage alongside broader technology themes including AI, cybersecurity, market shifts and early signals in quantum computing.
