Researchers at the University of Innsbruck, where the quantum simulator came from, have discovered a way to design a quantum computer free from perturbations. Previous research has shown how to create quantum states from what normally increases disorder; dissipation. The Innsbruck researchers used this and a new concept in condensed matter physics called topological order. An example topological phenomenon is the topological insulator which conductor on its surface while being an insulator inside. The combination of these two sciences allows the researchers to describe a quantum mechanical system which will be driven to a targeted state by dissipation. This development may lead to quantum computers immune to the disturbances of dissipation, making them more viable in the future.
