Quantum secure direct communication (QSDC) is an important branch of quantum communication, based on the principles of quantum mechanics for the direct transmission of classified information. While recent proof-of-principle ...
Inside a drop of paint, light is scattered so often that it seems impossible to demonstrate quantum effects. But despite the thousands of possible paths the light can take, like a drunk person inside a labyrinth, researchers ...

In a new report now published in Science Advances, Andrey Jarmola and an international research team in physics and materials in the U.S. and Germany demonstrated the function of a rotation sensor based on the Nitrogen-14 ...
In quantum electrodynamics, the choice of gauge (i.e. specific mathematical formalism used to regulate degrees of freedom) can greatly influence the form of light-matter interactions. Interestingly, however, the "gauge invariance" ...
The quantum world and our everyday world are very different places. In a publication that appeared as the "Editor's Suggestion" in Physical Review A this week, UvA physicists Jasper van Wezel and Lotte Mertens and their colleagues ...
