During the mid- to late-twentieth century, quantum physicists picked apart the unified theory of physics that Einstein’s theory of relativity offered. The physics of the large was governed by gravity, ...

Auger electron spectroscopy is a well-established surface-sensitive technique. It has been mostly used for the identification of species on sample surfaces, especially to monitor the process of sample ...

Uncertainty affects the accuracy with which measurements can be made in quantum physics. To reduce this uncertainty, physicists have learned to "squeeze" certain measurements. Researchers are now ...

Physics at the smallest scales is a challenge of observation: Particles are often fleeting, and the forces that govern their behavior are nearly imperceptible. But now, by exploiting decades-old data ...

Korean researchers have successfully established a measurement protection (MP) theory that enables stable quantum key ...

With a dedicated monthly column, Nature Physics draws attention to metrology. And a set of Commentaries in this issue focuses on various aspects of thermometry. Physics is all about observations, ...

A method for characterizing quantum measurement devices completes the suite of 'tomography techniques', which should enable us to learn all there is to know about a given quantum-physics experiment. A ...

The Franklin Institute announced Nov. 11 that it is awarding the 2026 Benjamin Franklin Medal in Physics, one of the nation’s ...

Quantum physics, celebrated for its predictive success, has also become notorious for being an inscrutable mass of paradoxes. One of the founders of the theory, Niels Bohr, stated that "those who are ...

Hickory dickory dock, this nucleus could make a great clock. A special variety of the element thorium hosts an atomic nucleus that could be used to keep time, scientists say. In a first, researchers ...
