# Recovering quantum correlations from amplitude damping decoherence by weak measurement reversal

Recovering quantum correlations from amplitude damping decoherence by weak measurement reversal We consider a weak measurement reversal proposal to recover quantum correlations of two-qubit system under local amplitude damping channels. With weak measurement reversal, we show that quantum correlations do not vanish but preserve a finite value in the limit of the noise strength $$p\rightarrow 1$$ , which can be attributed to the probabilistic nature of this method. The experimental feasibility of this approach is also discussed in pure optical systems. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Quantum Information Processing Springer Journals

### Abstract

We consider a weak measurement reversal proposal to recover quantum correlations of two-qubit system under local amplitude damping channels. With weak measurement reversal, we show that quantum correlations do not vanish but preserve a finite value in the limit of the noise strength $$p\rightarrow 1$$ , which can be attributed to the probabilistic nature of this method. The experimental feasibility of this approach is also discussed in pure optical systems.
