Qubits require a high degree of isolation from their environment to prevent decoherence, a phenomenon where quantum information is lost due to interactions with the surroundings. Nanomaterials can be designed to minimize these interactions. For example, silicon-based nanostructures can be used to create qubits with long coherence times. Additionally, topological insulators are another class of nanomaterials that can support robust qubits less susceptible to decoherence due to their unique surface states.
