"provides non-contact detection method for quantum states, relevant for qubits in topological quantum computing... Molecular Beam Epitaxy grown V-doped (Bi,Sb)₂Te₃ optimized for high-temperature quantum anomalous Hall effect without external magnetic fields, due to intrinsic magnetization/ chiral edge states... pure Coulomb coupling (no tunneling)... Majorana-based qubit interferometry, key topological quantum computing component... magnetization dynamics may lead to low-power, chiral electronic devices"
