    "abstract": "We report on experimental studies on entanglement quantification and\nverification based on uncertainty relations for systems consisting of two\nqubits. The new proposed measure is shown to be invariant under local unitary\ntransformations, by which entanglement quantification is implemented for\ntwo-qubit pure states. The nonlocal uncertainty relations for two-qubit pure\nstates are also used for entanglement verification which serves as a basic\nproposition and promise to be a good choice for verification of multipartite\nentanglement.",
