* These defects are referred to as tunneling two-level systems (TLSs) and are important for making quantum computers work better.
* The study introduces a new method to change TLS properties by creating an acoustic bandgap, which helps reduce noise and increases relaxation time for quantum devices significantly.
Protected qubits such as the 0-π qubit, and bosonic qubits including cat qubits and Gottesman-Kitaev-Preskill (GKP) qubits offer advantages for fault tolerance. Some of these protected qubits (e.g.
