Future cosmic microwave background (CMB) experiments are primarily targeting a detection of the primordial $B$-mode polarisation. The faintness of this signal requires exquisite control of systematic effects which may bias the measurements. In this w

Lie algebraic invariants in quantum linear optics

Autor: Parellada, Pablo V., Garcia, Vicent Gimeno i, Moyano-Fernández, Julio José, Garcia-Escartin, Juan Carlos

Quantum linear optics is a promising candidate for obtaining a quantum computational advantage. However, linear optics without post-selection is not powerful enough to produce any quantum state from a given input state. This limits its utility since

Large angular scale surveys in the absence of atmosphere are essential for measuring the primordial $B$-mode power spectrum of the Cosmic Microwave Background (CMB). Since this proposed measurement is about three to four orders of magnitude fainter t

Unexplained correlation between the Cosmic Microwave Background temperature and the local matter density distribution

Autor: Cruz, M., Martínez-González, E., Gimeno-Amo, C., Kavanagh, B. J., Tucci, M.

Recent observations have indicated a Cosmic Microwave Background (CMB) temperature decrement in the direction of local galaxies within the 2MASS Redshift Survey. We investigate this detection by analyzing its frequency dependence and sensitivity to c

Tailored Design of Audio-Visual Speech Recognition Models using Branchformers

Autor: Gimeno-Gómez, David, Martínez-Hinarejos, Carlos-D.

Recent advances in Audio-Visual Speech Recognition (AVSR) have led to unprecedented achievements in the field, improving the robustness of this type of system in adverse, noisy environments. In most cases, this task has been addressed through the des
