The General Conference on Weights and Measures (CGPM, for its acronym in French), which oversees the International System of Units (SI) system, will redefine four basic scientific units in November 2018: ampere, kilogram, kelvin and mol . The changes will take effect in May 2019. This is the largest revision of the IS since the…… Continue reading Interview at RNE of Prof. Miguel Angel Martin-Delgado (QUITEMAD cordinator), together with José Ángel Robles and Emilio Prieto (CEM)

Belén Franch, 34, has been awarded by the US agency for her work against climate change and hunger in the world. Franch is currently an associate scientist at the aerospace agency and, since 2013, a professor at the University of Maryland. Her research focuses on two fields, one more theoretical and linked to climate change and…… Continue reading NASA rewards a Spanish physical woman

Researchers have generated a Bose-Einstein condensate aboard a rocket, which is an important step in designing extremely accurate gravitational wave sensors.These condensates are not an invention of solitary library mice. They were proposed in 1925 and, when technology finally advanced enough, they became reality for the first time in 1995. Now, thanks to the latest…… Continue reading They manage to create a strange form of matter in space for the first time

German and North American researchers have managed to control the quantum states of molecules, opening the door to a new technology that will help the processing of quantum information and increase the control of chemical reactions. They have achieved this by joining a molecule to an atom, which they used to manipulate the molecule. More…… Continue reading They get for the first time the quantum control of a molecule

The examination of this elementary particle with unprecedented precision supports, once again, the standard model of physics. Researchers at Imperial College London concluded in 2011 that the electron is the most perfect sphere in the Universe. As announced, what separates this elementary particle from the absolute roundness is less than 0.000000000000000000000000001 cm, something insignificant. Now,…… Continue reading The electron remains the most perfect sphere in the Universe

The properties of graphene allow communications with a large bandwidth while maintaining a low power consumption, which radically improves the transmission of data in optical systems. Integrated photon-based graphene devices are becoming a promising solution for the next generation of optical communications. The properties of this carbon material allow transmitting information with a high bandwidth…… Continue reading Integrated graphene photonics for next-generation communications

Swiss scientists find the key to quantum memory: they have discovered that the ytterbium, a chemical element of the periodic table, subjected to precise magnetic fields, is able to isolate itself from the environment and operate at high frequencies, thus allowing it to store and replicate the quantum signal quickly and build a global quantum…… Continue reading The ytterbium will allow the construction of a global quantum network
