Permutationally invariant quantum tomography
Geza Toth, Witlef Wieczorek, David Gross +3
We present a scalable method for the tomography of large multiqubit quantum registers. It acquires information about the permutationally invariant part of the density operator, whi…

Addendum to "Sufficient conditions for three-particle entanglement and their tests in recent experiments"
Geza Toth, Otfried Guehne, Michael Seevinck +1
A recent paper [M. Seevinck and J. Uffink, Phys. Rev. A 65, 012107 (2002)] presented a bound for the three-qubit Mermin inequality such that the violation of this bound indicates g…
