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…

Factorisation conditions and causality for local measurements in QFT
Robin Simmons, Maria Papageorgiou, Marios Christodoulou +1
Quantum operations that are perfectly admissible in non-relativistic quantum theory can enable signalling between spacelike separated regions when naively imported into quantum fie…
