Quantum tomography via compressed sensing: error bounds, sample complexity and efficient estimators

ST Flammia, D Gross, YK Liu, J Eisert - New Journal of Physics, 2012 - iopscience.iop.org
Intuitively, if a density operator has small rank, then it should be easier to estimate from
experimental data, since in this case only a few eigenvectors need to be learned. We prove …

Resource-efficient high-dimensional entanglement detection via symmetric projections

S Morelli, M Huber, A Tavakoli - Physical Review Letters, 2023 - APS
We introduce two families of criteria for detecting and quantifying the entanglement of a
bipartite quantum state of arbitrary local dimension. The first is based on measurements in …
