We develop a new technique, based on Stein’s method, for comparing two stationary distributions of irreducible Markov chains whose update rules are close in a certain sense.We apply this technique to ...

Zebras and tigers have stripes, cheetahs and leopards have spots, and the ocellated lizard (Timon lepidus) boasts a labyrinthine pattern of black-and-green chains of scales. Now researchers from the ...

Combinatorial optimization problems are at the root of many industrial processes and solving them is key to a more sustainable and efficient future. Ising machines can solve certain combinatorial ...

Theoretical physicists develop mathematical models to describe material systems, which they can then use to make predictions about how materials will behave. One of the most important models is the ...

Researchers at the NTT Research Physics and Informatics (PHI) Lab and Tohoku University co-author paper outlining the capabilities of single photon Coherent Ising Machines (CIM). Paper reports ...

The central selling point of qubit-based quantum processors is that they can supposedly solve certain types of tasks much faster than a classical computer. This comes however with the major ...

These models differ by the constrains given to the orientation of the electron's spins (arrows). If all spins are aligned in one direction, the material becomes a ferromagnet. Below the magnetic ...
