Alternate qubit design does error correction in hardware
Briefly

Nord Quantique has demonstrated error correction using a single qubit with a distinct hardware design. While this has the potential to greatly reduce the number of hardware qubits needed for useful error correction, the demonstration involved a single qubit.
But on Thursday, a company called Nord Quantique announced that it had demonstrated error correction using a single qubit with a distinct hardware design.
The technology underlying this work is termed a bosonic qubit, and they're not anything new; an optical instrument company even has a product listing for them that notes their potential for use in error correction.
