Optimized decoherence suppression of two qubits in independent non-Markovian environments using weak measurement and quantum measurement reversal

In this paper, the dynamics of concurrence and quantum discord (QD) for the Werner state in independent non-Markovian environment is investigated. Our result manifests that QD reveal more properties about quantum correlations than concurrence for the given system. Additionally, an optimal scheme is proposed to suppress decoherence by performing prior weak measurement and post-measurement reversal. It is worth noticing that the effect of our scheme is better for the larger measurement strengths, and the stronger decoherence suppression induces smaller selection probability.
