Abstract

Suppression of quantum decoherence is a critical issue in quantum information processing. Weak measurement can protect entanglement under decoherence in inertial frames. Here, we study how to protect entanglement in non-inertial frames, because there is no strict inertial frames, decoherence and loss of the entanglement generated by the Unruh effect will influence each other remarkably, so it is important to discover some methods to protect entanglement in non-inertial frames.
