Extracting GHZ states from linear cluster states
Physical Review ResearchQuantum information processing architectures typically only allow for nearest-neighbor entanglement creation. In many cases, this prevents the direct generation of GHZ states, which are commonly used for many communication and computation tasks. Here, we show how to obtain GHZ states between nodes in a network that are connected in a straight line ...

Multi-Party Quantum Secret Sharing Based on GHZ State. [PDF]
Entropy (Basel), 2022 In this paper, we propose an efficient multi-party quantum secret sharing scheme based on GHZ entangled state. The participants in this scheme are divided into two groups, and share secrets as a group.

Protecting quantum Fisher information of N-qubit GHZ state by weak measurement with flips against dissipation. [PDF]
Sci Rep, 2017 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 ...
