\([[10,2,3]]\) binarized Galois-qudit code[1]
Description
CSS code obtained by binarizing a \([[5,1,3]]_4\) Galois-qudit CSS code in the self-dual normal basis \(\{\omega,\omega^2\}\).
A stabilizer tableau for the binarized code is [1] \begin{align} \begin{array}{cccccccccc} Z & I & Z & I & Z & I & Z & I & I & I \\ I & Z & I & Z & I & Z & I & Z & I & I \\ I & I & Z & I & Z & Z & I & Z & Z & I \\ I & I & I & Z & Z & I & Z & Z & I & Z \\ X & I & X & I & X & I & X & I & I & I \\ I & X & I & X & I & X & I & X & I & I \\ I & I & X & I & I & X & X & X & X & I \\ I & I & I & X & X & X & X & I & I & X \end{array}~. \tag*{(1)}\end{align}
Transversal Gates
The code is permutation-equivalent to its Hadamard dual: transversal physical Hadamards followed by swapping the two qubits in each binarized \(\mathbb{F}_4\) coordinate preserve the codespace and implement a logical \(H^{\otimes 2}\) up to logical \(\mathrm{SWAP}\). This is the binarized version of the permutation-assisted Hadamard available from plain self-duality of the starting \(q=4\) Galois-qudit CSS code [1].Cousins
- Binarized-and-concatenated (B&C) phantom code— The binarized \([[10,2,3]]\) code is not phantom, but concatenating each qubit pair with the \([[4,2,2]]\) code yields a \([[20,2,6]]\) B&C phantom code admitting fold-diagonal logical \(SS\) gates [1].
- \([[4,2,2]]\) Four-qubit code— Concatenating each qubit pair of the binarized \([[10,2,3]]\) code with the \([[4,2,2]]\) code yields a \([[20,2,6]]\) phantom code [1].
- \([[5,1,3]]_4\) Galois-qudit CSS code— Binarizing the \([[5,1,3]]_4\) code in the self-dual normal basis \(\{\omega,\omega^2\}\) yields a \([[10,2,3]]\) qubit CSS code [1].
