Impossible measurements require impossible apparatus

Understand

A well-recognised open conceptual problem in relativistic quantum field theory concerns the relation between measurement and causality.

Naive generalisations of quantum measurement rules can allow for superluminal signalling ('impossible measurements').
This raises the problem of delineating physically allowed quantum measurements and operations.
We analyse this issue in a recently proposed framework in which local measurements (in possibly curved spacetime) are described physically by coupling the system to a probe.

The stated Haag property could be strengthened to incorporate all (possibly disconnected) regions L L containing K K . However it might then conflict with a further desirable property called additivity , see p. 146 in [ 9 ]
