Device enables direct communication among multiple quantum processors
Massachusetts Institute of TechnologyPeer-Reviewed Publication
MIT researchers developed a scalable interconnect that facilitates all-to-all communication among many quantum processor modules by enabling each to send and receive quantum information on demand in a user-specified direction. They used the interconnect to demonstrate remote entanglement, a type of correlation that is key to creating a powerful, distributed network of quantum processors.

Pollutants often originate in the air
Paul Scherrer InstitutePeer-Reviewed Publication
At CERN, the European Organisation for Nuclear Research in Geneva, an international research team led by the Paul Scherrer Institute PSI has conducted especially precise measurements of atmospheric chemistry. Through this study the researchers were able to show how harmful particulate matter arises from vehicular emissions and biomass combustion. Their findings are helping to make existing models of particle formation more accurate.

Relax, I'm cool
Kyoto UniversityPeer-Reviewed Publication
Kyoto, Japan -- The Mpemba effect, in which hot systems cool faster than cold ones under the same conditions, was first described by Aristotle more than 2,000 years ago. In 1963 it was rediscovered by Tanzanian student Erasto Mpemba, who observed it when preparing ice cream in a cooking class at school. Mpemba later collaborated with British physicist Denis Osborne on a paper that described its effect on water.
Since Mpemba and Osborne's influential research, further studies have demonstrated that the effect extends beyond simple liquids and can be observed in a variety of physical systems --even microscopic ones. Yet one fundamental challenge has persisted; the detection of the Mpemba effect depends on the choice of a specific distance measure.
An infinite number of distance measures exist, so observing the effect using one distance measure may not materialize within a finite time when evaluated with another. Conventional methods typically assess relaxation speed, which is the rate of return to equilibrium after a change in temperature -- by using a single monotone measure -- but this often leads to inconsistent results.
