Bulk and Boundary Quantum Phase Transitions in a Square Rydberg Atom Array

Marcin Kalinowski, Rhine Samajdar, Roger G. Melko +3

Motivated by recent experimental realizations of exotic phases of matter on programmable quantum simulators, we carry out a comprehensive theoretical study of quantum phase transit…

Near-optimal covariant quantum error-correcting codes from random unitaries with symmetries

Linghang Kong, Zi-Wen Liu

Quantum error correction and symmetries play central roles in quantum information science and physics. It is known that quantum error-correcting codes that obey (are covariant with…

Perspective-neutral approach to quantum frame covariance for general symmetry groups

Anne-Catherine de la Hamette, Thomas D. Galley, Philipp A. Hoehn +2

In the absence of external relata, internal quantum reference frames (QRFs) appear widely in the literature on quantum gravity, gauge theories and quantum foundations. Here, we ext…

The Relational Interpretation of Quantum Physics

Carlo Rovelli

The relational interpretation (or RQM, for Relational Quantum Mechanics) solves the measurement problem by considering an ontology of sparse relative events, or "facts". Facts are…

General features of the thermalization of particle detectors and the Unruh effect

T. Rick Perche

We study the thermalization of smeared particle detectors that couple locally to operator in a quantum field theory in curved spacetimes. We show that if the field state sati…

Measurements in QFT: Weakly coupled local particle detectors and entanglement harvesting

Daniel Grimmer, Bruno de S. L. Torres, Eduardo Martín-Martínez

We present a comparison of the AQFT-based Fewster-Verch framework with the Unruh-DeWitt particle detector models commonly employed in relativistic quantum information and QFT in cu…
