Experimental verification of bound and multiparticle entanglement with the randomized measurement toolbox
Chao Zhang, Yuan-Yuan Zhao, Nikolai Wyderka +10
In recent years, analysis methods for quantum states based on randomized measurements have been investigated extensively. Still, in the experimental implementations these methods w…
Characterizing crosstalk of superconducting transmon processors
Andreas Ketterer, Thomas Wellens
Currently available quantum computing hardware based on superconducting transmon architectures realizes networks of hundreds of qubits with the possibility of controlled nearest-ne…
Complete characterization of quantum correlations by randomized measurements
Nikolai Wyderka, Andreas Ketterer, Satoya Imai +5
The fact that quantum mechanics predicts stronger correlations than classical physics is an essential cornerstone of quantum information processing. Indeed, these quantum correlati…
Probing the geometry of correlation matrices with randomized measurements
Nikolai Wyderka, Andreas Ketterer
The generalized Bloch decomposition of a bipartite quantum state gives rise to a correlation matrix whose singular values provide rich information about non-local properties of the…
Quantifying multiparticle entanglement with randomized measurements
Sophia Ohnemus, Heinz-Peter Breuer, Andreas Ketterer
Randomized measurements constitute a simple measurement primitive that exploits the information encoded in the outcome statistics of samples of local quantum measurements defined t…
Statistically significant tests of multiparticle quantum correlations based on randomized measurements
Andreas Ketterer, Satoya Imai, Nikolai Wyderka +1
We consider statistical methods based on finite samples of locally randomized measurements in order to certify different degrees of multiparticle entanglement in intermediate-scale…
