Effective master equations for two accelerated qubits
Greg Kaplanek, Erickson Tjoa
We revisit the problem involving two constantly accelerating Unruh-DeWitt detectors using Open Effective Field Theory methods. We study the time evolution of the joint detector sta…
Non-perturbative simple-generated interactions with a quantum field for arbitrary Gaussian states
Erickson Tjoa
In this work we first collect and generalize several existing non-perturbative models for the interaction between a single two-level qubit detector and a relativistic quantum scala…
Quantum teleportation with relativistic communication from first principles
Erickson Tjoa
In this work we provide a genuine relativistic quantum teleportation protocol whose classical communication component makes use of relativistic causal propagation of a quantum fiel…
Fermi two-atom problem: non-perturbative approach via relativistic quantum information and algebraic quantum field theory
Erickson Tjoa
In this work we revisit the famous Fermi two-atom problem, which concerns how relativistic causality impacts atomic transition probabilities, using the tools from relativistic quan…
Modest holography and bulk reconstruction in asymptotically flat spacetimes
Erickson Tjoa, Finnian Gray
In this work we present a "modest" holographic reconstruction of the bulk geometry in asymptotically flat spacetime using the two-point correlators of boundary quantum field theory…
Unruh-DeWitt detector in dimensionally-reduced static spherically symmetric spacetimes
Erickson Tjoa, Robert B. Mann
We study the dynamics of an Unruh-DeWitt detector interacting with a massless scalar field in an arbitrary static spherically symmetric spacetimes whose metric is characterised by…
Holographic reconstruction of asymptotically flat spacetimes
Erickson Tjoa, Finnian Gray
We present a "holographic" reconstruction of bulk spacetime geometry using correlation functions of a massless field living at the "future boundary" of the spacetime, namely future…
Channel capacity of relativistic quantum communication with rapid interaction
Erickson Tjoa, Kensuke Gallock-Yoshimura
In this work we study nonperturbatively the transmission of classical and quantum information in globally hyperbolic spacetimes, where the communication channel is between two qubi…
