Topological protection refers to the phenomenon in certain quantum systems where the system's properties remain robust against small perturbations or disturbances due to their topological nature. This concept is crucial in understanding topological superconductors, as it leads to the stability of Majorana fermions, which are expected to exhibit non-Abelian statistics and are promising candidates for fault-tolerant quantum computing. The resilience of these states arises from the underlying topology of the system, allowing them to maintain coherence even in the presence of defects or noise.
congrats on reading the definition of Topological Protection. now let's actually learn it.
