How does the principle of monogamy of entanglement restrict the sharing of entangled states among multiple particles?

The monogamy of entanglement principle states that if two particles are maximally entangled with each other, they cannot be entangled with a third particle. This restriction ensures that entanglement cannot be freely shared among multiple particles, limiting the distribution of entanglement and thus playing a crucial role in the structure of quantum networks and the security of quantum communication protocols.
