This is an interesting advance for quantum computers, but I think we'll see real progress when it will be possible to build qubits in a fully solid state form at room temperature and beyond like modern computer chips are currently made and with very few errors. Note that even in current CPUs and RAM there are errors, but these are handled by dedicated hardware, are invisible to the rest of the system and often don't even lead to a slowdown in performance, being fixed in realtime. In fact, the latest DDR5 RAM is inherently prone to errors so uses internal ECC to prevent those from reaching the output.

Future quantum computers could use bizarre 'error-free' qubit design built on forgotten research from the 1990s
Qubits can be made by floating a suspended electron over a pool of liquid helium rather than being embedded them a solid-state crystal — which leads to impurities and errors.
