The discovery of superconductivity more than a century ago has significantly changed our world.
Quantum entanglement is the basic phenomenon underlying the functioning of a variety of quantum systems, including quantum communication, quantum sensing and quantum computing tools. This phenomenon results from an interaction ...
Researchers at the Department of Energy's Oak Ridge National Laboratory used quantum optics to advance state-of-the-art microscopy and illuminate a path to detecting material properties with greater sensitivity than is possible ...

A group of physicists at the University of Basel, in Switzerland, has found via experimentation that the Einstein-Podolsky-Rosen paradox still holds even when scaled up. Paolo Colciaghi, Yifan Li, Philipp Treutlein and Tilman ...
In the quantum world, the famous Heisenberg uncertainty principle bounds the product of the variances of two incompatible observables such as the position and the momentum of a particle by the Planck constant. Heisenberg, ...

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 ...
Quantum information relies on the possibility of writing messages in a quantum particle and reading them out in a reliable way. If, however, the particle is relativistic, meaning that it moves with velocities close to the ...
