The Structure of Circle Graph States
Frederik Hahn, Rose McCarty, Hendrik Poulsen Nautrup +1
Circle graph states are a structurally important family of graph states. The family's entanglement is a priori high enough to allow for universal measurement-based quantum computat…

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…

The Foliage Partition: An Easy-to-Compute LC-Invariant for Graph States
Adam Burchardt, Frederik Hahn
This paper introduces the foliage partition, an easy-to-compute LC-invariant for graph states, of computational complexity in the number of qubits. Inspired by t…
