XP stabilizer code[1]
Description
The XP Stabilizer formalism is a generalization of the XS and Pauli stabilizer formalisms, with stabilizer generators taken from the group \( \{\omega I, X, P\}^{\otimes n} \). Here, \( \omega \) is a \( 2N \) root of unity, and \( P = \text{diag} ( 1, \omega^2) \). The codespace is a \(+1\) eigenspace of a set of XP stabilizer generators, which need not commute to define a valid codespace.
XP stabilizer codes are classified into XP-regular and XP-non-regular, where the former can be mapped to a CSS code with similar logical operator structure.

Children
- XS stabilizer code — The XP stabilizer formalism reduces to the XS formalism at \(N=4\).
- Qubit stabilizer code — The XP stabilizer formalism reduces to the Pauli formalism at \(N=2\).
Cousins
- Calderbank-Shor-Steane (CSS) stabilizer code — Each XP-regular code can be mapped to a CSS code with a similar logical operator structure [1].
- Codeword stabilized (CWS) code — The orbit representatives of XP codes play a similar role to the word operators of CWS codes.
