Yoked surface code[1]
Description
Member of a family of \([[n,k,d]]\) qubit CSS codes resulting from a concatenation of a QMDPC code with a rotated surface code. Concatenation does not impose additional connectivity constraints and can triple the number of logical qubits per physical qubit when compared to the original surface code. Concatenation with 1D (2D) QMDPC yields codes with twice (four times) the distance. Using the concatenation convention of the Zoo, the stabilizer generators of the inner QMDPC code are referred to as yokes in this context; the cited paper [1] uses the opposite inner/outer terminology.Primary Hierarchy
Parents
Using the concatenation convention of the Zoo, a yoked surface code is a concatenation of a QMDPC code (inner code) with a rotated surface code (outer code). The cited paper [1] uses the opposite inner/outer terminology.
