Digital Euro: A (Digital) Symbol of Progress and Integration in Europe

The emergence of crypto assets such as Bitcoin and Ether exposed a number of advantages that these digital assets based on distributed ledger technology (DLTs) can offer. As cash is becoming less and less popular in the eurozone, the European Central Bank (ECB) is currently looking at the scenario of creating a digital euro as a kind of central bank money that may be used by the general public. DLT may be used to tokenize central bank money via digital currencies (CBDCs) issued by central banks, as well as to digitally represent bank deposits. The purpose of this article is to analyse what are the solutions for the future digitization of the monetary and financial systems and if current CBDC projects and prototypes, including those by the Chinese and Swedish central banks and the attempts of the ECB, have the chance to succeed with or without DLT.

Wireless to optical phase mapping in a seamless digital wireless-photonic link

This paper investigates the seamless mapping of wireless mmWave phase-levels to the optical phase-levels in a seamless digital mmWave-to-photonic converter. We report a non-linear mapping of phase-levels from the wireless to the optical domain which results in digital symbol degeneracy. Our work provides various optimum design guidelines to make such seamless converters practically feasible in digital communication links. The latency and the design complexity of such a seamless converter are expected to be appreciably lower than those of a conventional converter, thereby making it more suitable for 6G communication systems. Although the wireless operating frequency considered in this paper belongs to the mmWave band, all the contributions presented are equally applicable and relevant in the THz wireless band as well.

Quick Response Journey // Viaje de respuesta rápida

The Quick Response Journey installation is inspired by the QR code (a matrix to store and encode high volumes of data) that is becoming more and more familiar to all of us due to the increasing use of portable electronics. A QR code contains information with fast readability, it is a digital symbol of our times. Digitalised. Virtualised. Dematerialised. But on the other hand, our adaptation as humans is not as fast as technology is. Nowadays we are devoted to the technology, apparently it is important for us. We have faith in tech. This QR code is materialised to go in and experience a metaphorical journey, an ultra-fast pilgrimage trying to balance our primitive and technological needs. We start the journey entering from the carbon society. While we walk through the green corridor we absorb all the condensed amount of data of living nature. The same QR code is in the centre inside an illuminated box from the bottom full of sprouts, symbols of nature and inspiration to reverse the destruction of the earth going towards a post-carbon society. Resumen La instalación de Viaje de respuesta rápida está inspirada en el código QR (una matriz para almacenar y codificar gran cantidad de datos), que se está volviendo cada vez más conocido para todos debido a su uso en aumento en sistemas electrónicos portátiles. Un ´código QR contiene información de rápida legibilidad, es un símbolo digital de nuestra época. Digitalizado. Virtualizado. Desmaterializado. Pero por otro lado, nuestra adaptación como humanos no es tan rápida como la tecnología. Hoy en día estamos dedicados a la tecnología, aparentemente es importante para nosotros. Tenemos fe en ella. Este código QR se materializa para ir en un viaje metafórico y para experimentarlo, un peregrinaje ultra rápido que intenta equilibrar nuestras necesidades primitivas y tecnológicas. Empezamos el viaje entrando desde la sociedad de carbono. Mientras caminamos por el pasillo verde absorbemos todas las cantidades de datos condensadas de la naturaleza viva. El mismo código QR está en el centro de una caja iluminada desde abajo, llena de brotes, símbolos de la naturaleza e inspiración para revertir la destrucción de la tierra yendo hacia una sociedad post-carbono.
