Protecting quantum Fisher information of N-qubit GHZ state by weak measurement with flips against dissipation
Abstract In this paper we propose a scheme by using weak-measurement-based pre- and post-flips (WMPPF) to protect the average quantum Fisher information (QFI) in the independent amplitude-damping channel (ADC) for N-qubit GHZ state and generalized N-qubit GHZ states. We also discuss the weak measure...
