Vishveshwara, S. (2011). Topological qubits: A bit of both. Nat. Phys., 7, 450–451.
Abstract: 'Standard' qubits have been implemented in diverse physical systems. Now, so-called topological qubits are coming into the limelight, and could potentially be used for decoherence-free quantum computing. Coupling these two types of qubit might enable devices that exploit the virtues of both.
