Causality and realizability of local operations in quantum field theory
Jan Mandrysch, Robin Simmons, Miguel Navascues
The paper analyzes which local quantum operations are allowed in relativistic quantum field theory, showing that some causal channels cannot be approximated by existing FV schemes…

Relative entropy for locally squeezed states
Daniela Cadamuro, Markus B. Fröb, Dimitrios Katsinis +1
Relative entropy serves as a fundamental measure of state distinguishability in both quantum information theory and relativistic quantum field theory. Despite its conceptual import…

Quantum Field Measurements in the Fewster-Verch Framework
Jan Mandrysch, Miguel Navascués
The Fewster-Verch (FV) framework provides a local and covariant approach for defining measurements in quantum field theory (QFT). Within this framework, a probe QFT represents the…
