Real Classical Shadows with Noise
Atharva Hingane, Dax Enshan Koh
The real classical shadows protocol of West et al. replaces the unitary (Clifford) ensemble of the Huang--Kueng--Preskill scheme by the orthogonal (real Clifford) ensemble, and for…

Exact calculation of entanglement negativity for a 1+1D massless scalar field using phase space methods
Jason Pye, Atharva Hingane, Robert H. Jonsson
Quantum fields exhibit a rich entanglement structure which is still not fully understood. In this work, we study the entanglement structure of the vacuum state of a massless scalar…

The negativity core of a 1+1D massless scalar quantum field
Jason Pye, Atharva Hingane, Robert H. Jonsson
Vacuum entanglement is a fundamental feature of quantum field theory exhibiting rich structure that is not completely understood. Here, we provide a complete characterization of th…
