Physics and information are intimately connected, and the ultimate information processing
devices will be those that harness the principles of quantum mechanics. Many physical …

We describe two implementations of the optimal error correction algorithm known as the
maximum likelihood decoder (MLD) for the two-dimensional surface code with a noiseless …

Quantum computers promise computational advantages for many important problems
