Description
Quantum code whose construction is non-deterministic in some way, i.e., codes that utilize an elements of randomness somewhere in their construction. Members of this class range from fully non-deterministic codes (e.g., random-circuit codes), to codes whose multi-step construction is deterministic with the exception of a single step (e.g., expander lifter-product codes).Cousins
- Random code
- Bosonic rotation code— Random bosonic rotation codes can outperform cat and binomial codes when loss rate is large relative to dephasing rate [2].
- NTRU-GKP code— Several NTRU lattices come from randomized constructions, yielding constant-rate GKP code families whose largest decodable displacement length scales as \(O(\sqrt{n})\) with high probability.
- Covariant block quantum code— Random \(U(1)\)-covariant [3] and \(U(d)\)-covariant [4,5] approximate QECCs exist.
- Quantum locally recoverable code (QLRC)— Random QLRCs with qudit dimension \(q = 2^{O(r)}\) achieve a relative distance that is order \(O(1/r)\) below the Singleton-like QLRC bound [6; Prop. 5].
