Quantum signatures of black hole mass superpositions
Joshua Foo, Cemile Senem Arabaci, Magdalena Zych +1
We present a new operational framework for studying ``superpositions of spacetimes'', which are of fundamental interest in the development of a theory of quantum gravity. Our appro…
On the duality of Schwarzschild-de Sitter spacetime and moving mirror
Diego Fernández-Silvestre, Joshua Foo, Michael R. R. Good
The Schwarzschild-de Sitter (SdS) metric is the simplest spacetime solution in general relativity with both a black hole event horizon and a cosmological event horizon. Since the S…
Relativistic Bohmian trajectories of photons via weak measurements
Joshua Foo, Estelle Asmodelle, Austin P. Lund +1
Bohmian mechanics is a nonlocal hidden-variable interpretation of quantum theory which predicts that particles follow deterministic trajectories in spacetime. Historically, the stu…
Telefilters, telemirrors, and causality
Joshua Foo, Sho Onoe, Magdalena Zych +1
We present new theoretical models for quantum optical mode-selective filters and mirrors using continuous-variable teleportation. We call these devices telefilters and telemirrors…
Entanglement amplification between superposed detectors in flat and curved spacetimes
Joshua Foo, Robert B. Mann, Magdalena Zych
We consider an entanglement harvesting protocol between two Unruh-deWitt detectors in quantum superpositions of static trajectories in the static de Sitter and thermal Minkowski sp…
