Experimental measurement of bipartite entanglement using parameterized quantum circuits

Entanglement in quantum systems plays a crucial role in various quantum information tasks. Measuring entanglement has been an important issue in both experiments and theories. In this work, we use parameterized quantum circuits (PQCs) to diagonalize density matrices of quantum states and obtain enta...
