Description
Approximate \(n\)-fermionic code whose codewords are low-energy states of the Sachdev-Ye-Kitaev (SYK) Hamiltonian [3,4] or other low-rank SYK models [5,6].

- Fermion code
- Approximate quantum error-correcting code (AQECC) — SYK codes are approximately error correcting in that they satisfy certain error-correction conditions based on mutual information [2].
- Hamiltonian-based code — The SYK code Hamiltonian is constructed out of non-commuting few-site terms, and every fermion participates in many interactions.
- Holographic code — In a holographic model [2], the large distance of these codes can be interpreted as being due to the emergence of a wormhole.
Cousin
- Kim-Preskill-Tang (KPT) code — The Brownian SYK model can be used to demonstrate the complexity-based error-correction of KPT codes [7].
