When you lookup "surface code" the first thing that comes up is "toric code". Off hand there's the toric code, the 3d toric code, welded toric code, color codes, and the surface code itself (which is a lattice of "measure qubits" next to a lattice of "data qubits"). The basic idea on all of them is the same as Kitaev's original insight of topologically protected data. IMO its completely fair to lump these together as "surface codes".
If you disagree with my choice of words then I'm happy to concede and rephrase. If something else I said doesn't sound kosher please by all means lmk.
- selimthegrim 11y agoNo, he's correct. In addition I would add that passive error correction is taking leaps and bounds lately, making dephasing essentially a non issue in multi-qubit systems (scalability is yet to be fully manifested)
- IIAOPSW 11y agocorrect in what respect? I'm not trying to be rude here but it is unclear what exactly I'm being called out on. Do you disagree with my use of the word "surface codes" or do you disagree with the way I've lumped a bunch of QEC's together under one name? Or is the disagreement something else entirely. And yeah I'm aware of the advances in passive QEC. Exciting time to be alive!
