Experimental test of Kubo relation on a non-linear quantum conductor from energy exchanges

Experimental test of Kubo relation on a non-linear quantum conductor from energy exchangesNanoLab_NanoTech
Speaker Carles Altemiras (SPEC, Université Paris-Saclay, UMR3680 CEA – CNRS)
Date: 14/06/2024 
Place: aula I Edificio del Trilingüe (Facultad de Ciencias, Universidad de Salamanca) 11:00 a 12:00 h
Abstract:
We present an experimental test of Kubo formula on a non-linear quantum conductor, a Superconducting-Insulator-Superconducting tunnel junction, driven far from equilibrium by a dc voltage bias. Following the proposal of Lesovik & Loosen, we first demonstrate it is possible to extract both emission and absorption noise of the conductor by measuring the power it exchanges with a linear detection circuit whose population is tuned close to vacuum levels. We then compare their difference to the real part of the admittance, which is independently measured by coherent reflectometry, finding that Kubo relation holds within experimental accuracy.

Characterization of Quantum Non-demolition Measurements of Superconducting Qubits

Characterization of Quantum Non-demolition Measurements of Superconducting Qubits
Speaker: Tomás Ramos (CSIC QUINFOG Madrid)  https://quinfog.hbar.es/members/tomas-ramos/
Fecha, lugar y hora: 14/06/2024, aula I Edificio del Trilingüe (Facultad de Ciencias, Universidad de Salamanca) 10:00 a 11:00 h
Abstract:
The current generation of quantum machines can perform universal quantum logic operations, but the number of successive operations is limited by noise, imperfections, and decoherence. My work focuses on improving the quality of quantum measurement and amplification in superconducting circuits, which induces the largest errors at the moment (on order 1%). In this seminar, I will first review the standard procedure for dispersive qubit readout and then discuss new tomographic methods to experimentally reconstruct the complete quantum process behind a quantum non-demolition (QND) measurement [1,2]. This provides valuable information to identify measurement errors, and we show how to use this to improve the calibration of dispersive superconducting qubit, quantify more precisely the QNDness and back-action of the measurement, as well as to characterize multi-qubit parity measurements needed in quantum error correcting codes.

Why do galaxy sizes matter? by Fernando Buitrago

Speaker: Fernando Buitrago (Universidad de Valladolid)Title: Why do galaxy sizes matter?

Abstract: During the last decades, galaxy sizes have been a very active research topic in Astrophysics given the fact that they are one of the few direct observables from objects in the distant Universe. In this seminar, I will review the different approaches that were traditionally taken, showing what we have learned about how our Universe works over time. However, galaxies are fuzzy objects, and as such it is very hard to assign sizes to them. One would naively think that by observing for larger integration times and/or by using better telescopes these objects will grow bigger and bigger. I will prove you wrong by describing a novel physically-motivated size proxy (the galaxy edges or galaxy truncations) that my team GEELSBE (Galactic Edges and Euclid in the Low Surface Brightness Era) at the University of Valladolid is studying. We have utilized the deepest pointings of the Hubble Space Telescope (while now using the James Webb Space Telescope and Machine Learning algorithms) to obtain the evolution of this parameter last 8 Gyr promising to give us first hand information not only about the baryonic mass assembly but also the dark matter halo evolution.

Robust constraints in Cosmology with a very large public repository of science-ready LSS data

Title: Robust constraints in Cosmology with a very large public repository of science-ready LSS data
CarlosGarciaGarcia
Abstract: In this talk I will present an ongoing work towards building a very large public repository containing data
from virtually all relevant projected large-scale-structure datasets, consistently re-analysed under a common data analysis framework. The repository consists of a large number of angular power spectra and their uncertainties, combining a wide variety of tracers of interesting quantities for cosmology and astrophysics. I will showcase novel results in cosmology and astrophysics that have been enabled by this framework, such as constraints on the amplitude of matter fluctuations that are competitive with Stage-4 surveys, the reconstruction of the cosmic growth history or constraints on baryonic effects.
