Summary: Topological insulator Josephson junctions' localized Andreev bound states support fault-tolerant topological quantum computation. Couples topological insulator thin films with superconducting electrodes within closed phase-control loop, isolating protected Majorana 0 modes against decoherence. Hardware developers provided with crucial design parameters to fabricate fault-tolerant topological qubits that inherently resist environmental phase noise and operational bit flips.
