Unruh phenomena and thermalization for qudit detectors
Caroline Lima, Everett Patterson, Erickson Tjoa +1
We study Unruh phenomena for a qudit detector coupled to a quantized scalar field, comparing its response to that of a standard qubit-based Unruh-DeWitt detector. We show that ther…

Wigner function for quantum field theory via spacetime tiling
Erickson Tjoa
We present a construction of the Wigner function for a bosonic quantum field theory that has well-defined ultraviolet (UV) and infrared (IR) properties. Our construction uses the l…

Fuzzy spacetime: fundamental limits of quantum-optical holographic bulk reconstruction
Erickson Tjoa
In this Essay we construct a concrete, non-perturbative realization of metric reconstruction using quantum-optical model of particle detectors in relativistic quantum information.…
