Do fewer gravitational waves occur than expected?

Researchers from the University of Jaén (UJA) and the University of Barcelona (UB) have discovered for the first time a structure in the form of Z in a microquasar. The finding can be extrapolated to the study of radiogalaxies and the background of gravitational waves that, the study suggests, could be weaker than previously estimated.…… Continue reading Do fewer gravitational waves occur than expected?

New technique that allows to know the density of defects in sheets of graphene

A researcher from the Polytechnic University of Madrid (UPM) has collaborated in the development of a method to determine the density of defects in two-dimensional nanomaterials thanks to measures of the changes in the spatial coherence of the light that is made to influence them. In an article published in the journal Optica, researchers at…… Continue reading New technique that allows to know the density of defects in sheets of graphene

A quantum leap for ultraprecise measurement and information coding

An EU-funded project dedicated to ultrafast optics has expanded the control that is held over the spatial-temporal quantum states of light and made progress in the quantum information sciences. The science of quantum information could be of great help for metrology and for different systems of information and communication technology. However, the degree of control…… Continue reading A quantum leap for ultraprecise measurement and information coding

How to create a hybrid quantum network between different laboratories

Researchers from the Institute of Photonic Sciences have achieved an elementary link in a hybrid quantum network, formed by cold atoms and a crystal with ions, and using a photon as the carrier of information. This is how photonic quantum communication between two quantum nodes of a different nature and placed in different laboratories has…… Continue reading How to create a hybrid quantum network between different laboratories

Create a ‘data bus’ for quantum computing

The difference between conventional computing and quantum computing is comparable to needing decades and even more time to solve problems in the case of conventional computing, instead of just a few minutes in the case of quantum computing. Quantum computers will be able to perform jobs that even the most powerful supercomputers and conventional computer…… Continue reading Create a ‘data bus’ for quantum computing

Three-Dimensional Nanomagnets for the computer of tomorrow

Since the late 60´s electronic devices have stored and transmitted information (bits) in two-dimensional circuits. Now, researchers at the University of Cambridge have been able to break this barrier by creating a nanoscale magnetic circuit capable of moving information along the three dimensions of space. This breakthrough could lead to an important increase in storage…… Continue reading Three-Dimensional Nanomagnets for the computer of tomorrow
