From power grids to epidemics: Study shows how small patterns trigger systemic failures

Why do some systems collapse suddenly after what seems like a minor disturbance? A single transmission line failure can ...

Simplifying quantum simulations—symmetry can cut computational effort by several orders of magnitude

Quantum computer research is advancing at a rapid pace. Today's devices, however, still have significant limitations: For example, the length of a quantum computation is severely limited—that is, the ...
