  Quantum entanglement between an arbitrary number of remote qubits is examined
analytically. We show that there is a non-probabilistic way to address in one
context the management of entanglement of an arbitrary number of mixed-state
qubits by engaging quantitative measures of entanglement and a specific
external control mechanism. Both all-party entanglement and weak inseparability
are considered. We show that for $N\ge4$, the death of all-party entanglement
is permanent after an initial collapse. In contrast, weak inseparability can be
deterministically managed for an arbitrarily large number of qubits almost
indefinitely. Our result suggests a picture of the path that the system
traverses in the Hilbert space.
