Quantum light engine links atom-photon thermodynamics to classical physics
What is heat, and what is useful work if a machine consists only of an atom and light particles? In modern quantum technologies, this kind of question connects thermodynamics with quantum physics. Researchers at the University of Basel, Switzerland, have developed a theoretical approach that can reconcile both theories.Quantum Physics NewsRead More
Three photons at once beat the standard photon test
Physicists at the University of Twente have improved the standard test for the quality of individual particles of light. By letting three photons interfere at the same time instead of two, they draw more information from every measurement. Their experiment outperforms even a perfect, noise-free run of the old method. The work appeared in Physical
Gluons may play a central role in baryon number conservation—and matter’s stability
New results from the STAR detector at the Relativistic Heavy Ion Collider (RHIC) suggest that gluons, the glue-like particles that hold quarks together inside protons, play a central role in the conservation of baryon number—an essential part of a particle’s quantum identity.Quantum Physics NewsRead More
