A team of researchers affiliated with several institutions in China has found that quantum key distribution (QKD) networks can be used to accurately measure ground vibration. In their paper published in the journal Physical Review Letters, the group describes their implementation of a twin-field, fiber-based QKD network over a distance of 658 km. They also determined that…… Continue reading Quantum key distribution network accurately measures ground vibration

Physicists at EPFL, within a large European collaboration, have revised one of the fundamental laws that has been foundational to plasma and fusion research for over three decades, even governing the design of megaprojects like ITER. The update shows that we can actually safely use more hydrogen fuel in fusion reactors, and therefore obtain more…… Continue reading A new law unchains fusion energy

Can energy move from a colder to a hotter region in a material without violating the second law of thermodynamics? Yes, according to physicists from Trinity College Dublin and the Universidad Complutense of Madrid, who discovered that a quantum effect sometimes forces current to flow around the edges of a sample in a way that…… Continue reading Energy can move from a colder region to a hotter one – but the second law of thermodynamics is safe

MIT research scientists Pablo Rodriguez-Fernandez and Nathan Howard have just completed one of the most demanding calculations in fusion science—predicting the temperature and density profiles of a magnetically confined plasma via first-principles simulation of plasma turbulence. Solving this problem by brute force is beyond the capabilities of even the most advanced supercomputers. Instead, the researchers…… Continue reading Machine learning, harnessed to extreme computing, aids fusion energy development

Entre las aplicaciones del patrón primario se encuentra el estudio de la corteza terrestre

In physics, as in life, it’s always good to look at things from different perspectives

The Prime Matters workshop aims to bring together world experts in theoretical condensed matter, quantum information and statistical physics. These three areas of physics have many points of contact. The systems integrable are the basis for understanding many condensed matter systems, which also benefit of an approach typical of quantum information theory, based on entanglement…… Continue reading WORKSHOP “PRIME MATTERS”
