How long does it take to obtain a physical density matrix?
Lukas Knips, Christian Schwemmer, Nico Klein +3
The statistical nature of measurements alone easily causes unphysical estimates in quantum state tomography. We show that multinomial or Poissonian noise results in eigenvalue dist…

Quadratic Entanglement Criteria for Qutrits
Krzysztof Rosołek, Marcin Wieśniak, Lukas Knips
The problem of detecting non-classical correlations of states of many qudits is incomparably more involved than in a case of qubits. The reason is that for qubits we have a conveni…
