Transmission of quantum information through quantum fields in curved spacetimes
Michael Kasprzak, Erickson Tjoa
We construct a relativistic quantum communication channel between two localized qubit systems, mediated by a relativistic quantum field, that can achieve the theoretical maximum fo…

Particle detectors under chronological hazard
Ana Alonso-Serrano, Erickson Tjoa, Luis J. Garay +1
We analyze how the presence of closed timelike curves (CTCs) characterizing a time machine can be discerned by placing a local particle detector in a region of spacetime which is c…

The Unruh-DeWitt model and its joint interacting Hilbert space
Erickson Tjoa, Finnian Gray
In this work we make the connection between the Unruh-DeWitt particle detector model applied to quantum field theory in curved spacetimes and the rigorous construction of the spin-…
