There have been several experimental realizations of CSS-based codes. The first demonstration was with nuclear magnetic resonance qubits. Subsequently, demonstrations have been made with linear optics, trapped ions, and superconducting (transmon) qubits. • In 2016 for the first time the lifetime of a quantum bit was prolonged by employing a QEC code. • In 2021, an entangling gate between two logical qubits encoded in topological quantum error-correction codes ha
