The graviton - the quantum particle of gravity

Igor Pikovski has been interviewed by Swedish Radio about how they will use a small supercold resonance box and quantum sensor technology to detect gravitons. They believe that gravitons can be detected using quantum sensor technology. These particles have previously been considered impossible to observe. Igor Pikovski is a senior lecturer at the Department of Physics.

How to catch a graviton

Gravitons, the quantum particles of gravity, were thought to be impossible to observe. Scientists have now worked out how they can be detected by using quantum sensing technology.

Quantum Connections Summer School at Högberga for the thirteenth time

This year's summer school runs from 9 to 22 June at Högberga konferensgård on Lidingö outside Stockholm. About fifty participants will come there to deepen their knowledge. It is a summer school organized for PhD students and postdocs, both theoretical and experimental, in all aspects of quantum limits. Nobel Laureate Frank Wilczek, Professor at Fysikum and Professor Antti Niemi, Nordita are the initiators of the summer school.

Frank's curiosity has earned him the Nobel Prize and several fruitful collaborations

Professor Frank Wilczek's was interested in mathematics and big numbers even as a child. His father was an electrical technician who fixed radios and tvs when they were broken. Frank was inspired and liked to take apart and put together things to see how they worked. This was the beginning of a fantastic career in Physics. In 2004, Wilczek received the highest honor in science — the Nobel Prize in Physics — for his discovery of asymptotic freedom and the development of the theory of quantum chromodynamics (QCD). Since 2016 he has been working at the Department of Physics.

David Marsh is Vice Director of EuCAPT

EuCAPT is a European consortium for astroparticle theory. It aims to bring together European researchers in theoretical astroparticle physics and cosmology. In early February, David Marsh took over as Vice Director of the consortium. At Fysikum he is a researcher in astroparticle physics and teaches the course Quantum Phenomena and Radiation Physics.

A Plasma Haloscope for the Post-Inflation Axion

In Fall 2022, a consortium of the Simons Foundation, the Alfred P. Sloan Foundation, the John Templeton Foundation and the Gordon and Betty Moore Foundation published a solicitation seeking to make profound advancements in physics by means of Small-Experiments of “table-top” size. The proposal “A Plasma Haloscope for the Post-Inflation Axion”, lead by the Berkely group has been announced as one of the 11 awardees among hundreds of initial proposals, for which a total of $30M over five years has been pledged by the foundations. “With this funding and also the earlier funding by the Knut and Alice Wallenberg Foundation we’re ready to start developing and building this detector that has the potential to discover axions”, says Jón Gudmundsson, senior researcher at Stockholm and current spokesperson of the ALPHA collaboration.

Workshop about exploring simulations of gravity and quantum gravity

In July Fysikum hosted a workshop in Stockholm, jointly organized by Igor Pikovski from Fysikum and Rivka Bekenstein from the Hebrew University of Jerusalem. Its focus was the study of quantum gravity in the lab. 20 participants spent 3 days at Näsby Slott to discuss quantum simulations and quantum aspects of gravity.

The Future is Quantum: 20 - 22 February 2023

An emerging field of physics and engineering is quantum technology, encompassing technologies that rely on the properties of quantum mechanics. Quantum computing being one example of these technologies, representing a paradigm shift for computing technology, since it can outperform much more than existing computers. On February 21 at 13:00, in the: Svedberg salen (FD5), AlbaNova, Professor Akira Furusawa from University of Tokyo, RIKEN Center for Quantum Computing will have a presentation with the title THE FUTURE IS QUANTUM - The development of Quantum Computing.
