Entanglement and the truncated moment problem
Fabian Bohnet-Waldraff, Daniel Braun, Olivier Giraud
We map the quantum entanglement problem onto the mathematically well-studied truncated moment problem. This yields a necessary and sufficient condition for separability that can be…
Regularly Decomposable Tensors and Classical Spin States
Liqun Qi, Guofeng Zhang, Daniel Braun +2
A spin- state can be represented by a symmetric tensor of order and dimension . Here, can be a positive integer, which corresponds to a boson; can also be a po…
Tensor eigenvalues and entanglement of symmetric states
Fabian Bohnet-Waldraff, Daniel Braun, Olivier Giraud
Tensor eigenvalues and eigenvectors have been introduced in the recent mathematical literature as a generalization of the usual matrix eigenvalues and eigenvectors. We apply this f…
Partial transpose criteria for symmetric states
Fabian Bohnet-Waldraff, Daniel Braun, Olivier Giraud
We express the positive partial transpose (PPT) separability criterion for symmetric states of multi-qubit systems in terms of matrix inequalities based on the recently introduced…
Quantumness of spin-1 states
Fabian Bohnet-Waldraff, Daniel Braun, Olivier Giraud
We investigate quantumness of spin-1 states, defined as the Hilbert-Schmidt distance to the convex hull of spin coherent states. We derive its analytic expression in the case of pu…
