Enhanced quantum resilience through twists
Quantum technology will revolutionize information transmission, processing, and sensing with unprecedented potential for science, economy, and the society as a whole. Yet, the strong sensitivity of quantum systems to unavoidable environmental noise impedes quantum technological breakthroughs. Here, we propose to twist coupled elemental quantum systems such that they form a global, robust quantum state that is resilient against environmental perturbations. For instance, in magnetic spin chains, fixing the magnetization at one end while rotating the magnetization at the other end can result in stable quantum helices. Such quantum twists cannot easily be unwound: They exhibit topological…
