Core Concepts
This research paper presents a novel, efficient tomography method for characterizing large cluster states of entangled photonic qubits, demonstrating its effectiveness by reconstructing the density matrices of cluster states with up to 35 microwave photonic qubits and analyzing their entanglement properties.
