Desde el Grupo de Termodinámica y Computación Cuántica de la Universida de Granada les invitamos al siguiente seminario. Ponente: Dr. Joseph Dunlop (QTCG-UGR) Fecha y Hora: Viernes 15 de Mayo. 12:00 Lugar: Seminario de Física Computacional. Planta baja del edificio de Física. Facultad de Ciencias. Title: Higher order quantum operations part 1: constructive approach Abstract: Quantum mechanical systems are described by states, which can be transformed into other states via channels. We here ask: what transformations can the channels themselves undergo, within the laws of quantum mechanics? This will lead us to the notion of higher order quantum operations (HOQOs), a hierarchy of transformations starting from superchannels which map channels to channels, quantum combs which map superchannels to superchannels, and so on. In this first seminar we will cover the so-called constructive approach, in which we will see how HOQOs can be composed in quantum circuits, introduce the formalism to describe HOQOs as Choi operators, and see how physical properties of the HOQOs (such as causal ordering) translate into constraints on their operator representation.
