Sudden death and revival of Gaussian Einstein–Podolsky–Rosen steering in noisy channels
Abstract Einstein–Podolsky–Rosen (EPR) steering is a useful resource for secure quantum information tasks. It is crucial to investigate the effect of inevitable loss and noise in quantum channels on EPR steering. We analyze and experimentally demonstrate the influence of purity of quantum states and...
