Quantum 'magic' could help explain the origin of spacetime

A quantum property dubbed "magic" could be the key to explaining how space and time emerged, a new mathematical analysis by three RIKEN physicists suggests. The research is published in the journal Physical Review D.

Quantum chemistry: Molecules caught tunneling

Tunneling reactions in chemistry are difficult to predict. The quantum mechanically exact description of chemical reactions with more than three particles is difficult, with more than four particles it is almost impossible. ...

How to reverse unknown quantum processes

In the world around us, processes appear to follow a certain time-direction: Dandelions eventually turn into blowballs. However, the quantum realm does not play by the same rules. Physicists from the University of Vienna ...

The first lab-created 'quantum abacus'

Do you want to know whether a very large integer is a prime number or not? Or if it is a "lucky number"? A new study by SISSA, carried out in collaboration with the University of Trieste and the University of Saint Andrews, ...

An enhanced cooling method for the quantum world

The quantum nature of objects visible to the naked eye is currently a much-discussed research question. A team led by Innsbruck physicist Gerhard Kirchmair has now demonstrated a new method in the laboratory that could make ...

Mini-engine exploits noise to convert information into fuel

Too much background noise is usually guaranteed to disrupt work. But physicists have developed a micro-scale engine–made from a glass bead–that can not only withstand the distracting influence of noise, but can harness ...
