On the need for topological quantum computation in quantum computation:

• Sankar Das Sarma, Quantum computing has a hype problem, MIT Technology Review (March 2022)

  The qubit systems we have today are a tremendous scientific achievement, but they take us no closer to having a quantum computer that can solve a problem that anybody cares about. […] What is missing is the breakthrough $[\cdots]$ bypassing quantum error correction by using far-more-stable qubits, in an approach called topological quantum computing.
