Researchers at the University of Basel and the Laboratoire Kastler Brossel have demonstrated how quantum mechanical ...

Quantum state diffusion framework makes it possible to characterize quantum measurement in terms of entropy production ...

Entangled atoms, separated in space, are giving scientists a powerful new way to measure the world with stunning precision.

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, ...

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 ...

An international team of researchers has systematically measured the β-decay half-lives of 40 nuclei near calcium-54, ...

We know how to derive most fundamental constants from conditions of the universe, models This is an accurate description of physics as a whole, but wildly untrue in particle physics. There are 25 ...

The 50-foot-wide racetrack used to study muons traveled by barge around Florida and up the Mississippi, and then by truck across Illinois. Reidar Hahn, Fermilab About 50 years ago, physicists came up ...

This morning on BBC Radio 4, the mathematician Roger Penrose, physicist Basil Hiley, and philosopher Simon Saunders had a lively discussion about the “measurement problem in physics” with broadcaster ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.
