Inducing multipartite entanglement revival in dissipative environment by means of prior quantum uncollapsing measurements

• We propose a way for inducing multipartite entanglement revival from decoherence.
• The effect is more pronounced for the given system with less initial entanglement.
• Our scheme also works for the NN-qubit GHZ-class state.

A scheme for inducing multipartite entanglement revival in the dissipative environment is proposed, which is implemented by performing a prior quantum uncollapsing (weak measurements or measurement reversals) procedure on partial qubits of the system simultaneously. This procedure preferentially equips our initial states, and make them hold more powerful ability to actively battle against degradation of entanglement, even postpone entanglement sudden death (ESD). Notably, the effect is more pronounced for the multipartite system with less initial entanglement. In addition, we found that our scheme also works for the NN-qubit GHZ-class state.
