Let∣ Ψ⟩ be an arbitrary stabilizer state distributed between three remote parties, such that
each party holds several qubits. Let S be a stabilizer group of∣ Ψ⟩⁠. We show that∣ Ψ⟩ …

Good quantum codes, such as quantum MDS codes, are typically nondegenerate, meaning
that errors of small weight require active error-correction, which is-unfortunately-itself prone …
