Quantum optics is a well-established field that spans from fundamental physics to quantum information science. In the coming decade, areas including computation, communication and metrology are all ...

Scientists have, for the first time, experimentally proven that angular momentum is conserved even when a single photon splits into two, pushing quantum physics to its most fundamental limits. Using ...

A new method developed at the University of Bonn simplifies ultra-precise adjustment for quantum optics experiments. When individual atoms interact with each other, they often exhibit unusual behavior ...

Since it was first demonstrated in the 1960s, spontaneous parametric down-conversion (SPDC) has been at the center of many quantum optics experiments that test the fundamental laws of physics in ...

A property of laser light first predicted in 1963 by the future Nobel laureate Roy Glauber has been verified by physicists in Italy. Marco Bellini and colleagues from the University of Florence have ...

Since the early 20th century physicists have known that light carries momentum, but the way that this momentum changes as light passes through different media is much less clear. Two rival theories of ...

Convention has it that quantum mechanics and thermodynamics cannot be true simultaneously - so say scientists at the University of Twente ("UT"), The Netherlands. But now, in a new journal paper, UT ...
