Five-rotor code[1]
Description
Extension of the five-qubit stabilizer code to the integer alphabet, i.e., the angular momentum states of a planar rotor. The code is \(U(1)\)-covariant and ideal codewords are not normalizable.
Protection
Normalized codewords approximately protect against erasure while maintaining covariance [1].
Parents

- Cyclic quantum code
- Small-distance block quantum code
Cousin
- \([[5,1,3]]_{\mathbb{Z}_q}\) modular-qudit code — The five-rotor code is a rotor analogue of the five-qudit code.
