Data underpinning "Towards scalable active steering protocols for genuinely entangled state manifolds"

We provide the raw data used to produce plots shown in our paper "Towards scalable active steering protocols for genuinely entangled state manifolds". The data is structured by the corresponding figure in the manuscript. Subfolder structure for Fig. 4+5: number of qubits - connectivity (full or nearest-neighbor) - value of $\delta t$. Subfolder structure for Fig. 6: number of qubits Each folder contains the following files: Quantum Fisher Information: average, histogram, 3 single trajectories Phase: average, histogram, 1 single trajectory Output file For N<6 an additional file containing the average purity is present. An additional file summarizes the relevant data for Fig. 4+5. Abstract We introduce and analyze an active steering protocol designed to target multipartite entangled states. The protocol involves multiple qubits subjected to weak Bell pair measurements with active feedback, where the feedback operations are optimized to maximize the Quantum Fisher Information. Our scheme efficiently reaches a genuinely entangled one-parameter state manifold. Numerical simulations for systems with up to 22 qubits suggest that the protocol is scalable and allows high multipartite entanglement across the system.
