Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The ...

For almost a century, Heisenberg's uncertainty principle has stood as one of the defining ideas of quantum physics: a particle's position and momentum cannot be known at the same time with absolute ...

Physicists are now using a tightly controlled laser and a cloud of ultracold atoms to imitate the behavior of electrons in solids, effectively building a quantum version of electronics out of light ...

Quantum theory explains the behavior of matter and energy at the smallest scales, like atoms and subatomic particles. Unlike ...

A century after Werner Heisenberg first formulated the mathematical foundations of quantum mechanics, we stand witness to both unprecedented quantum breakthroughs and an equally unprecedented ...

It often feels like electronics will continue to get faster forever, but at some point the laws of physics will intervene to put a stop to that. Now scientists have calculated the ultimate speed limit ...

A collaboration between Stuart Parkin’s group at the Max Planck Institute of Microstructure Physics in Halle (Saale) and Claudia Felser’s group at the Max Planck Institute for Chemical Physics of ...

Landauer's principle is a thermodynamics concept also relevant in information theory, which states that erasing one bit of information from an information system results in the dissipation of at least ...

Study demonstrates a chiral fermionic valve that separates handedness via quantum geometry, enabling transport and interference without magnetic fields. (Nanowerk News) A collaboration between Stuart ...
