Quantum state measurement serves as a crucial step in quantum information tasks. In this work, we utilized the hyper-entangled state of two-photon polarization and path, and exploited the mathematical correlation between modulus and weak values to overcome the experimental challenges associated with extracting nonlocal weak values. As a result, we achieved the direct measurement of nonlocal entangled quantum states for the first time, which contributes to improving the efficiency of quantum state measurement for complex quantum systems. The total data size is 64 KB.
