Abstract
Monogamy of entanglement is an interesting property discovered recently in the context of multi-qubit entanglement. Here, we present a new kind of monogamous relations for pure quantum states of N qubits. By comparing the entanglement monogamy equality proposed by Coffman, Kundu, and Wootters, we prove that there exists a strict triangle relation for the three-qubit system. Since the entropy defines the entanglement of a pure state of a pair of quantum systems; therefore, using linear entropy, we conjecture that there is a polygon relation of many-qubit systems. We also formalize the general triangle relation for the three-qubit system.
