In the Becker-Döring model, aggregates grow or shrink by addition or removal of one-by-one particle at a time. Under certain conditions, very large aggregates emerge and are interpreted as a phase transition. We study stationary and quasi-stationary properties of the stochastic Becker-Döring model in the limit of infinite total number of particles, and compare with results from the deterministic nucleation theory. Our findings are largely inspired from recent results from stochastic chemical reaction network theory. > > Os agradezco si podéis enviarle esta información a gente que creáis que pueda estar interesada.

[CAMBIO DE HORA] Seminario: Symmetry in Quantum Information: From Protocols to Foundations
by Daniel Manzano 02 Dec '22

02 Dec '22

El grupo de Termodinámica y Computación Cuántica de la Universidad de Granada les invita al siguiente seminario (atentos al cambio de hora). Ponente: Michalis Skotiniotis. Universidad Autónoma de Barcelona. Fecha: Miércoles 7 de Diciembre. Hora: 12:30. Title: Symmetry in Quantum Information: From Protocols to Foundations Abstract: Information is physical! Be it classical or quantum information transmission, storage, processing, and retrieval is done by devices obeying physical principles subject to restrictions that arise, for example, by conservation laws. As such, it is imperative to understand the limitations such restrictions impose to information processing. In this talk I present a series of problems in quantum information theory where symmetry can be a hinderance and/or a blessing. I will demonstrate how one can exploit symmetry to construct realistic codes for transmitting both classical and quantum information down noisy channels, protocols for compressing and copying quantum circuits, as well as metrological schemes for imaging and time-keeping that operate at the quantum mechanical limit. More profoundly, I hope to convince you that symmetry, and symmetry alone, is enough to explain the absence of macroscopic quantum phenomena from our everyday experience.
