Recently, a novel approach to the protection of superconducting qubits has been proposed. The idea is to prevent errors at the \"hardware\" level, by building a fault-free (topologically protected) logical qubit from \"faulty\" physical qubits with properly engineered interactions between them. It has been predicted that the decoupling of a protected logical qubit from local noises would grow exponentially with the number of physical ","authors_text":"Benoit Doucot, David Olaya, Eva Dupont-Ferrier, Lev B.
