Experimental observation of complementary quantum resources in three-qubit states - dataset

Here we experimentally observe these trade-offs in a controllable three-qubit photonic system. Using full quantum-state tomography, we reconstruct a family of experimentally generated states transitioning between generalized GHZ, maximal-slice, and biseparable states.

We then determine all four resources from the same reconstructed density matrix. The measured values follow parameter-free theoretical trajectories calculated from the independently controlled settings of the optical elements and reproduce the theoretically predicted extremal boundaries. We further observe a systematic redistribution between genuine tripartite entanglement and bipartite Bell nonlocality.
