Let $N$ measurements concern functions of the same parameter, and disregard digitisation errors. After the measurements, suppose that the $N$-dimensional error is restricted to a c…

Let $\rho^{\otimes n}(\theta)$ be a smooth model of $n$ identical quantum systems, and let $F$ be the scaled information matrix of a measurement on this model. For a mixed-state sp…

Smeared-field causality conjecture. An ideal measurement of a smeared field should respect relativistic causality.

The hidden-measurement approach models a quantum measurement as arising from the actualization of an interaction selected from a collection of potential measurement interactions. A…
