Optimisation problems are common in everyday life, springing up across several fields, such as network routing, logistics, machine learning, and material science.<\/p>\n
These problems are extremely complex and difficult to solve using standard computers, so researchers have had to turn to other methods. The team used a process known as annealing, that can be used to model optimisation problems.<\/p>\n
The researchers have attempted to create annealing processors that mimic the magnetic orientation of atoms, known as \u2018spins\u2019. The spins orientate randomly at high temperatures, but as the temperature decreases, the spins line up to reach the minimum energy state.<\/p>\n
The team presented the first fully-coupled, large-scale quantum processor, comprising 512 fully connected spins. These systems are notoriously hard to implement and upscale, due to the sheer number of connections between spins that need to be considered.<\/p>\n
While using multiple fully connected chips in parallel was a potential solution to the scalability problem, this meant that too many wires needed to be implemented in between the chips.<\/p>\n
