Abstract
Suppose in a quantum network, there are qubits hold by Alice, Bob and Charlie, denoted by systems , and , respectively. We require the qubits to be described by a stabilizer state and assume the system is entangled with the combined system . An interesting question to ask is when it is possible to transfer all the entanglement to system and by local operation on and classical communication to , 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.
