Launched the cloud computing service "Annealing Cloud Web" using an annealing machine specialized for combinatorial optimization problem.

Welcome to Annealing Cloud Web

Annealing Cloud Web is operated by "Integrated Research and Development of Quantum Computation and Ising Computation Systems" project using the results of "Research and Development of Innovative Annealing Machines for Combinatorial Optimization" conducted by NEDO (New Energy and Industrial Technology Development Organization).
By allowing users to experience the annealing machine (Ising model type device), we aim to expand the user base, accelerate the development of related peripheral technologies (such as software), and improve the performance of the annealing machine itself.

CMOS annealing is a dedicated combinatorial optimization processing technology developed by HITACHI.

CMOS annealing machine is a non-Neumann architecture computer that Hitachi has developed by utilizing the structure of SRAM, a storage device, to perform optimization processing with the Ising model. Since the first prototype was released in 2015, there have been many series of products, including the ASIC version which uses King's graph and continues to update the world's best specifications, the FPGA versions, and the Momentum Annealing version which is now available in the market.
