Scientists have now mapped the forces acting inside a proton, showing in unprecedented detail how quarks—the tiny particles within—respond when hit by high-energy photons.
The international team includes experts from the University of Adelaide who are exploring the structure of sub-atomic matter to try and provide further insight into the forces that underpin the natural world.
“We have used a powerful computational technique called lattice quantum chromodynamics to map the forces acting inside a proton,” said Associate Professor Ross Young, Associate Head of Learning and Teaching, School of Physics, Chemistry and Earth Sciences, who is part of the team.
Photonics researchers from Tampere University, Finland, and Kastler-Brossel Laboratory, France, have demonstrated how self-imaging of light, a phenomenon known for nearly two centuries, can be applied to cylindrical systems, facilitating unprecedented control of light’s structure with great potential for advanced optical communication systems. In addition, a new type of space-time duality was explored for powerful analogies bridging different fields of optics.
In 1836, Henry F. Talbot performed an experiment, where he observed light patterns that naturally reappear after some propagation without the use of any lenses or imaging optics—a self-imaging phenomenon nowadays of then termed the Talbot effect.
Recently, researchers interested in sculpting light from the Experimental Quantum Optics Group (EQO) in Tampere University, as well as the Complex Media Optics group at Kastler Brossel Laboratory, in Ecole Normale Supérieure, Paris, have teamed up and investigated the self-imaging Talbot effect in cylindrical systems in greater depth than ever before. The presented interesting fundamental physics and powerful applications in optical communications have now been published in the journal Nature Photonics.
A breakthrough in quantum computing that could threaten crypto is still years away, but a new chip from Microsoft might have shortened that timeline, says Bitcoin platform River.

In this video I visited Microsoft’s quantum labs to see how they are making their topological quantum computers and learn how topology helps their quantum devices avoid noise by harnessing the power of Majorana quasiparticles which are made from an exotic form of superconductivity where the electrons behave like there is a Majorana particle there which has the special properties of topology.

Physicists have performed a groundbreaking simulation they say sheds new light on an elusive phenomenon that could determine the ultimate fate of the Universe.
Pioneering research in quantum field theory around 50 years ago proposed that the universe may be trapped in a false vacuum — meaning it appears stable but in fact could be on the verge of transitioning to an even more stable, true vacuum state. While this process could trigger a catastrophic change in the Universe’s structure, experts agree that predicting the timeline is challenging, but it is likely to occur over an astronomically long period, potentially spanning millions of years.
In an international collaboration between three research institutions, the team report gaining valuable insights into false vacuum decay — a process linked to the origins of the cosmos and the behaviour of particles at the smallest scales. The collaboration was led by Professor Zlatko Papic, from the University of Leeds, and Dr Jaka Vodeb, from Forschungszentrum Jülich, Germany.
