Using a superconducting circuit, they demonstrated a method to bypass an intermediate energy state without directly interacting with it—an advancement that could lead to more powerful and efficient quantum computing.

Capturing Electron Motion at Unthinkable Speeds
Electrons oscillate around the nucleus of an atom.
An atom is the smallest component of an element. It is made up of protons and neutrons within the nucleus, and electrons circling the nucleus.
Physicists suggest time may emerge from quantum entanglement, challenging traditional views of reality and the nature of the universe.

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.
