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…

Permutationally invariant state reconstruction
Tobias Moroder, Philipp Hyllus, Geza Toth +5
Feasible tomography schemes for large particle numbers must possess, besides an appropriate data acquisition protocol, also an efficient way to reconstruct the density operator fro…
