Title: Higher-order quantum operations

Abstract: An operational description of quantum phenomena concerns developing models that describe experimentally observed behaviour. Higher-order quantum operations—quantum operations that transform quantum operations—are fundamental to modern quantum theory, extending beyond basic state preparations, evolutions, and measurements described by the Born rule. These operations naturally emerge in quantum circuit architectures, correlated open dynamics, and investigations of quantum causality, to name but a few fields of application. In this talk, I will present a brief pedagogical introduction to the framework of higher-order quantum operations and present a few key results pertaining to non-Markovian open quantum dynamics, quantum functional programming, and causality in quantum theory.
