Separable Ball around any Full-Rank Multipartite Product State
Robin Yunfei Wen, Achim Kempf
We show that around any -partite product state of full rank (that is , there exists a finite-sized closed…
Quantum lattice models that preserve continuous translation symmetry
Dominic G. Lewis, Achim Kempf, Nicolas C. Menicucci
Bandlimited approaches to quantum field theory offer the tantalizing possibility of working with fields that are simultaneously both continuous and discrete via the Shannon Samplin…
Emergence of Spacetime from Fluctuations
Marcus Reitz, Barbara Šoda, Achim Kempf
We use a result of Hawking and Gilkey to define a Euclidean path integral of gravity and matter which has the special property of being independent of the choice of basis in the sp…
Lensing of Vacuum Entanglement near Schwarzschild Black Holes
João G. A. Caribé, Robert H. Jonsson, Marc Casals +2
An important feature of Schwarzschild spacetime is the presence of orbiting null geodesics and caustics. Their presence implies strong gravitational lensing effects for matter and…
Entanglement is better teleported than transmitted
Koji Yamaguchi, Achim Kempf
We show that, for the purpose of quantum communication via a quantum field, it is essential to view the field not only as a medium for transmission but also as a source of entangle…
The Transfer of Entanglement Negativity at the Onset of Interactions
Robin Yunfei Wen, Achim Kempf
Quantum information, in the form of entanglement with an ancilla, can be transmitted to a third system through interaction. Here, we investigate this process of entanglement transm…
