What is Fixstars Amplify AE?

Fixstars Amplify Annealing Engine (AE) is a Graphics Processing Unit (GPU)-based annealing machine. It can process large-scale problems consisting of more than 100,000 bits at high speed.  Although it is not based on quantum mechanical phenomena, it provides an ideal platform for easy PoC and development for practical applications, utilized for quantum annealing.

Performance

We solved the Traveling Salesman Problems (TSP), typical combinatorial optimization problems, to test performances of Amplify AE and other annealing machines. It is seen that Amplify AE quickly reaches the optimal solutions.
