Multipartite entanglement detection with minimal effort
Lukas Knips, Christian Schwemmer, Nico Klein +2
Certifying entanglement of a multipartite state is generally considered as a demanding task. Since an qubit state is parametrized by real numbers, one might naively e…
Genuine Multipartite Entanglement without Multipartite Correlations
Christian Schwemmer, Lukas Knips, Minh Cong Tran +4
Non-classical correlations between measurement results make entanglement the essence of quantum physics and the main resource for quantum information applications. Surprisingly, th…
Experimental Comparison of Efficient Tomography Schemes for a Six-Qubit State
Christian Schwemmer, Geza Toth, Alexander Niggebaum +4
Quantum state tomography suffers from the measurement effort increasing exponentially with the number of qubits. Here, we demonstrate permutationally invariant tomography for which…
