Publisher Correction: Topological antiferromagnetic spintronics

Antiferromagnetic metal spintronics.

In this brief review, we explain the theoretical basis for the notion that spin-transfer torques (STTs) and giant-magnetoresistance effects can, in principle, occur in circuits containing only normal and antiferromagnetic (AFM) materials, and for the notion that antiferromagnets can play a role in STT phenomena in circuits containing both ferromagnetic and AFM elements. We review the experiment...

Topological Quantum Error Correction

Interest in developing quantum computers stems from their ability to solve in polynomial time several important problems that are only classically solvable in exponential time. One significant hurdle facing the actual implementation of a quantum computer is the need for error correction code to make reliable quantum memory in the presence of errors, such as measurement errors and decoherence. H...

Topological Correction of Subcortical Segmentation

We propose a method for automatically correcting the spherical topology of any segmentation under any digital connectivity. A multiple region growing process, concurrently acting on the foreground and the background, divides the segmentation into connected components and successive minimum cost decisions guarantee convergence to correct spherical topology. In contrast to existing procedures tha...
