I was at first confused in that error correction is already in use. Then I realized that "qudits" is not a typo.
> A recent study by researchers from Yale University published in Nature created qudits—a quantum system that holds quantum information and can exist in more than two states. Using a qutrit (3-level quantum system) and a ququart (4-level quantum system), the researchers demonstrated the first-ever experimental quantum error correction for higher-dimensional quantum units using the Gottesman–Kitaev–Preskill (GKP) bosonic code.
I'll be interesting to see if these are more scalable than qubits or more applicable than decimal digital computer counterparts.
