Klobus, Waldemar; Cieslinski, Pawel; Knips, Lukas; Kurzynski, Pawel und Laskowski, Wieslaw (2021): Gaussian state entanglement witnessing through lossy compression. In: Physical Review A, Bd. 103, Nr. 3, 32412

Abstract

We study the possibility of witnessing Gaussian entanglement between two continuous-variable systems with the help of two spatially separated qubits. Its key ingredient is a local lossy state transfer from the original systems onto local qubits. The qubits are initially in a pure product state, therefore by detecting entanglement between the qubits we witness entanglement between the two original systems.
