Microsoft is taking a very complex but extremely promising approach to building quantum computers. In particular, Microsoft is using topological qubits, which are believed to be inherently more stable than qubits produced by other existing methods.

The recent discovery made by scientists at Microsoft shows that it is possible to harness quantum physics to produce topological qubits, proving the validity of the underlying theory.

While engineering challenges remain, this discovery turns out to be a key building block for a large-scale topological quantum computer.
