Finite Gaussian assistance protocols and a conic metric for extremizing spacelike vacuum entanglement
Boyu Gao, Natalie Klco
In a pure Gaussian tripartition, a range of entanglement between two parties () can be purified through classical communication of Gaussian measurements performed within the th…

Detecting spacelike vacuum entanglement at all distances and promoting negativity to a necessary and sufficient entanglement measure in many-body regimes
Boyu Gao, Natalie Klco
Though known to be present, the accessibility of spacelike vacuum entanglement capable of being a fundamental resource for quantum information processing has remained in question a…

Partial-transpose-guided entanglement classes and minimum noise filtering in many-body Gaussian quantum systems
Boyu Gao, Natalie Klco
The reduction and distortion of quantum correlations in the presence of classical noise leads to varied levels of inefficiency in the availability of entanglement as a resource for…
