A general estimation framework for continuous-variable systems
Luca Innocenti, Simone Artini, Diana A. Chisholm +5
We show that informational completeness, while sufficient to have a bijection between ideal measurement probabilities and quantum states, does not guarantee statistically stable re…

Metrological approach to the emergence of classical objectivity
Anthony Kiely, Diana A. Chisholm, Akram Touil +3
We present a precise characterization of the onset of classicality that combines the formalism of quantum Darwinism with the tools from quantum metrology. We show that the quantum…

On the emergence of quantum Darwinism and pointer states for non-commuting evolutions
Diana A. Chisholm, G. Massimo Palma, Luca Innocenti
Quantum systems achieve objectivity by redundantly encoding information about themselves into the surrounding environment, through a mechanism known as quantum Darwinism. When this…
