Hitachi

Hitachi Ltd. is a major Japanese multinational conglomerate founded in 1910, headquartered in Tokyo, developing quantum computing technologies including CMOS annealing and gate-type quantum computers. Hitachi started R&D on CMOS annealing machine in 2013, combining quantum annealing principles with CMOS technology creating quantum-inspired computers for combinatorial optimization problems. In 2020, Hitachi started R&D on silicon quantum computer as part of Japan's Moonshot Research and Development Program launched by Cabinet Office. In 2018, Hitachi partnered with University of Tokyo to develop high-speed quantum computer, and signed memorandum with Riken research institute and Belgian research organization to develop silicon-based quantum computer. In June 2024, Hitachi developed new qubit control method stabilizing and extending lifetimes by hundred-fold, accelerating quantum computer development. Hitachi offers CMOS Annealing Cloud Service for quasi-quantum computing serving enterprises requiring optimization solutions across logistics, finance, and industrial applications in Japan and globally.
