Dinur-Hsieh-Lin-Vidick (DHLV) code[1]
Description
A family of asymptotically good QLDPC codes which are related to expander LP codes in that the roles of the check operators and physical qubits are exchanged.
Rate
Asymptotically good QLDPC codes.
Decoding
Linear-time decoder utilizing the small set-flip decoder [2] for \(Z\) errors and a reconstruction procedure for \(X\) errors [1].
Parents
- Generalized homological-product qubit CSS code
- Lifted-product (LP) code — DHLV codes are LP codes [3; Footnote 7].
Cousins
- Good QLDPC code — DHLV code construction yields asymptotically good QLDPC codes.
- Regular binary Tanner code — Regular binary Tanner codes are used in constructing quantum DHLV codes.
- Tensor-product code — Tensor codes are used in constructing quantum DHLV codes.
- Balanced product (BP) code — DHLV codes can be obtained from a balanced product of two expander codes [3].
