Quantum steering ellipsoid visualizes the set of all qubit states that can besteered by measuring on another correlated qubit in the Bloch picture. Togetherwith local reduced states, it provides a faithful geometric characterization ofthe underlying two-qubit state so that almost all nonclassical state featurescan be reflected in its geometric properties. Consequently, the various typesof quantum ellipsoids with different geometric properties form an ellipsoidzoo, which, in this work, is experimentally verified via measurements on manypolarization-path photonic states. By generating two-qubit states with highfidelity, the corresponding ellipsoids are constructed to certify the presenceof entanglement, one-way Einstein-Podolsky-Rosen steering, discord, andsteering incompleteness. It is also experimentally verified that the steeringellipsoid can be reconstructed from using the twelve vertices of theicosahedron as measurement directions. Our results aid progress in applying thequantum steering ellipsoid to reveal nonclassical features of the multi-qubitsystem.
