Efficient measurement-device-independent detection of multipartite entanglement structure

Efficient measurement-device-independent detection of multipartite entanglement structure

Witnessing entanglement is crucial in quantum information processing. With properly preparing ancillary states, it has been shown previously that genuine entanglement can be witnessed without trusting measurement devices. In this work we generalize the scenario and show that generic multipartite entanglement structures, including entanglement of subsystems and entanglement depth, can …
