Experimental observation of complementary quantum resources in three-qubit states - dataset Martin Zeman (23627775) Eliška Romana Kaločová (25083124) Artur Barasiński (21496409) Karel Lemr (18367686) Jan Soubusta (21260817) Quantum information, computation and communication three qubits complementary relations coherence entanglement negativity steering Bell <p dir="ltr">Quantum resources such as entanglement, coherence, steering, and Bell nonlocality can coexist in a multipartite quantum state, but their simultaneous presence is constrained by quantitative complementarity relations. 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. Our results demonstrate that quantum-resource complementarity is experimentally observable and controllable in multipartite quantum states, providing a platform for studying the distribution and trade-offs of different quantum resources.</p> 2026-09-21T11:20:08Z Dataset Dataset 10.6084/m9.figshare.33952156.v1 https://figshare.com/articles/dataset/Experimental_observation_of_complementary_quantum_resources_in_three-qubit_states_-_dataset/33952156 CC BY 4.0
