About
Sigma-i is a Tokyo-based quantum computing startup founded in 2019 as a spinout from Tohoku University. It holds world-leading quantum annealing technologies and develops solutions that use quantum computers with annealing techniques. The company partners with Toppan on quantum computing research focused on logistics optimization. In 2021, Sigma-i and Toppan began pilot tests that used quantum annealing to improve the efficiency of logistics operations from pickup through to receipt of goods, with the goal of launching logistics DX solutions in 2025. The two companies also research overall optimization solutions based on quantum annealing for sectors beyond logistics. Sigma-i is part of Japan's growing quantum startup ecosystem, which received major government backing in 2025 with roughly 130 billion yen ($855 million) for quantum research and technology development.
