Systematic errors in current quantum state tomography tools
Christian Schwemmer, Lukas Knips, Daniel Richart +4
Common tools for obtaining physical density matrices in experimental quantum state tomography are shown here to cause systematic errors. For example, using maximum likelihood or le…
Optimized state independent entanglement detection based on geometrical threshold criterion
Wieslaw Laskowski, Christian Schwemmer, Daniel Richart +3
Experimental procedures are presented for the rapid detection of entanglement of unknown arbitrary quantum states. The methods are based on the entanglement criterion using accessi…
Experimental Schmidt Decomposition and Entanglement Detection
Wieslaw Laskowski, Daniel Richart, Christian Schwemmer +2
We introduce an experimental procedure for the detection of quantum entanglement of an unknown quantum state with as few measurements as possible. The method requires neither a pri…
