Are Ideal Measurements of Real Scalar Fields Causal?
Emma Albertini, Ian Jubb
Half a century ago a local and (seemingly) causally consistent implementation of the projection postulate was formulated for local projectors in Quantum Field Theory (QFT) by utili…

Causal State Updates in Real Scalar Quantum Field Theory
I. Jubb
In relativistic Quantum Field Theory (QFT) ideal measurements of certain observables are physically impossible without violating causality. This prompts two questions: i) can a giv…

Impossible measurements revisited
Leron Borsten, Ian Jubb, Graham Kells
It is by now well-recognised that the naïve application of the projection postulate on composite quantum systems can induce signalling between their constituent components, indicat…
