What Has Been Achieved:

Demonstration of SA to find the ground states of an Ising spin glass system. We use 2D material-based computing primitives to implement SA in an area- and energy efficient manner. Further, we use in-memory computing to increase the efficiency of this implementation.

Importance of the Achievement:

The development of novel hardware for SA would aid the general field of combinatorial optimization, where finding the optimal solution is extremely time/energy/area consuming without the use of such algorithms and hardware. Hence this could be used to optimize various tasks such as scheduling of transportation, supply chain logistics, and circuit design.

Unique Feature(s) of the MIP that Enabled this Achievement:

Dr. Joan Redwing’s group through 2DCC developed high-quality MoS2 films using MOCVD, which was crucial to our hardware development.
