Entanglement trimming in stabilizer formalism

Abstract

Suppose in a quantum network, there are nn qubits hold by Alice, Bob and Charlie, denoted by systems AA, BB and CC, respectively. We require the qubits to be described by a stabilizer state and assume the system AA is entangled with the combined system BCBC. An interesting question to ask is when it is possible to transfer all the entanglement to system AA and BB by local operation on CC and classical communication to ABAB, namely \textit{entanglement trimming}. We find a necessary and sufficient condition and prove constructively for this entanglement trimming, which we name it as "the bigger man principle". This principle is then extended to qudit with square-free dimension and continuous variable stabilizer states.
