Useful entanglement can be extracted from noisy graph states

Konrad Szymański, Lina Vandré, Otfried Gühne

Cluster states and graph states in general offer a useful model of the stabilizer formalism and a path toward the development of measurement-based quantum computation. Their defini…

Graph state extraction from two-dimensional cluster states

Julia Freund, Alexander Pirker, Lina Vandré +1

We propose schemes to extract arbitrary graph states from two-dimensional cluster states by locally manipulating the qubits solely via single-qubit measurements. We introduce graph…

Graphical Framework for Non-Gaussian Quantum States

Lina Vandré, Boxuan Jing, Yu Xiang +2

We provide a graphical method to describe and analyze non-Gaussian quantum states using a hypergraph framework. These states are pivotal resources for quantum computing, communicat…

Distinguishing Graph States by the Properties of Their Marginals

Lina Vandré, Jarn de Jong, Frederik Hahn +3

Graph states are a class of multi-partite entangled quantum states that are ubiquitous in quantum information. We study equivalence relations between graph states under local unita…

Algorithm to Verify Local Equivalence of Stabilizer States

Adam Burchardt, Jarn de Jong, Lina Vandré

We present an algorithm for verifying the local unitary (LU) equivalence of graph and stabilizer states. Our approach reduces the problem to solving a system of linear equations in…
