\([[5,1,3]]_{\mathbb{Z}_q}\) modular-qudit code

\([[5,1,3]]_{\mathbb{Z}_q}\) modular-qudit code[1,2]

Description

Modular-qudit stabilizer code that generalizes the five-qubit perfect code using properties of the multiplicative group \(\mathbb{Z}_q\) [1]; see also [2; Thm. 13]. It has four stabilizer generators consisting of \(X Z Z^\dagger X^\dagger I\) and its cyclic permutations.

The components of the encoding isometry in the computational basis (with \(a\) being the logical qubit index) are [3; Sec. VI.B] \begin{align} T_{aklmnp}=\delta_{a,k+l+m+n+p}^{\mathbb{Z}_{q}}\frac{1}{q^{2}}\omega^{kl+lm+mn+np+pk}~, \tag*{(1)}\end{align} where \(\omega\) is a primitive \(q\)th root of unity, and where \(\delta^{\mathbb{Z}_{q}}\) is the \(\mathbb{Z}_q\) Kronecker-delta function.

Protection

Protects against a single error on any one qudit. Detects two-qudit errors.

Encoding

Generalized CNOT, Toffoli, and quantum Fourier transform gates.

Cousins

Five-rotor code— The five-rotor code is a rotor analogue of the five-qudit code.
\([[10,1,4]]_{G}\) tenfold code— The \([[10,1,4]]_{G}\) Abelian group code for \(G=\mathbb{Z}_q\) is defined using a graph that is closely related to the \([[5,1,3]]_{\mathbb{Z}_q}\) modular-qudit code [4].
\([[5,1,3]]_{\mathbb{R}}\) Braunstein five-mode code— The Braunstein five-mode code is a bosonic analogue of the five-qudit code.

Perfect-tensor codeQECC Quantum

The \([[5,1,3]]_{\mathbb{Z}_q}\) code is a perfect-tensor code because it stems from the \([[6,0,4]]_{\mathbb{Z}_q}\) AME state [2; Thm. 13].

Graph quantum codeStabilizer Hamiltonian-based QECC Quantum

The \([[5,1,3]]_{\mathbb{Z}_q}\) code is equivalent via a single-modular-qudit Clifford circuit to a graph quantum code for the group \(G=Z_q\) [4].
