Physicists at MIT have designed a quantum "light squeezer" that reduces quantum noise in an incoming laser beam by 15 percent. It is the first system of its kind to work at room temperature, making it amenable to a compact, ...

A team of researchers from several institutions in Germany and Austria has developed a means for directly observing dynamical quantum phase transitions in an interacting many-body system. In their paper published in the journal ...
(Phys.org)—It was an interesting week for physics as Popper's experiment was realized again, by a different team this time, using a different approach, causing physicists to wonder what it actually means because the results ...
(Phys.org)—It was a very busy week for physics research. A team of scientists has set a quantum speed limit—the group at the University of California found a way to prove a fundamental relationship between energy and ...
University of California, Berkeley, scientists have proved a fundamental relationship between energy and time that sets a "quantum speed limit" on processes ranging from quantum computing and tunneling to optical switching.
