Talk on Friday May 05, 2023 at 11:00 Place: IFISC Seminar Room Title: Quantum Fisher Information and its dynamical nature Speaker: Matteo Scandi, ICFO Abstract: MdM Quantum Meeting The importance of the quantum Fisher information metric is testified by the number of applications that this has in very different fields, ranging from hypothesis testing to metrology, passing through thermodynamics. In this presentation, after a small technical introduction of the family of quantum Fisher information, I&#39;ll discuss a fact that was overseen in the literature, namely the inherently dynamical nature of Fisher information. This will be exemplified with three examples: first, the equivalence between positivity of a map and the contraction of Fisher information; second, the possibility of defining Markovianity (CP-divisibility) in the same manner; and finally, the definition of detailed balance as self-adjointness with respect to the Fisher information metric. The reference for the Markovianity part is: <a href="https://arxiv.org/pdf/2204.04072.pdf" target="_blank">https://arxiv.org/pdf/2204.04072.pdf</a>… Url event:https://ifisc.uib-csic.es/en/events/seminars/quantum-fisher-information-and-its-dynamical-natur/

Talk on Thursday Apr 27, 2023 at 11:00 Place: IFISC Seminar Room Title: Constructive effects of squeezing in loop-based quantum photonic architectures for quantum reservoir computing Speaker: Jorge García, IFISC Abstract: MdM Quantum Meeting Squeezing (field fluctuations below shot noise) is a quantum phenomenon that has proven to be key to several quantum technologies. In this talk, we will introduce quantum reservoir computing (QRC) based on an optical platform with a cavity to guarantee the presence of memory. We have studied the benefits of squeezing provided by a nonlinear crystal inside the cavity for time series processing. Concretely, we show that increasing the squeezing improves the reservoir robustness to readout noise. This enhances its accessible memory, which increases the performance in several benchmark tasks.

Talk on Friday Apr 21, 2023 at 12:00 Place: Zoom Seminar Title: Digital Platforms for a Sustainable World Speaker: Bruno Campanelli, IFISC, Sony Lab Rome. Abstract: Among the 17 sustainable development goals defined by the United Nations, the ninth one is to &ldquo;build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation&rdquo;, while the eleventh one is to &ldquo;make cities and human settlements inclusive, safe, resilient and sustainable&rdquo;. Two key factors contributing to a city&rsquo;s living standard are a well-functioning public transportation system, and high availability of services. In this talk I will illustrate two of the projects developed in the ongoing Digital Platforms for a Sustainable World collaboration between Sony Computer Science Laboratories Rome and Sapienza University of Rome. First, I will show&nbsp;how an agent-based approach, using GTFS-Realtime data, can be used to quantify the impact of public transportation delays on accessibility from the passengers&rsquo; point of view, focusing on the public transportation system of Rome . Then, I will present a toolset (relying on OpenStreetMap data) to quantify how close a city is to the 15-minute city ideal proposed by Carlos Moreno. Finally, I will show our in-development online platform that will allow citizens and stakeholders to visualize accessibility metrics and perform case studies.
