A technique known as a “weak measurement”, which allows physicists to measure certain properties of a quantum system without disturbing it, is being called into question by two physicists based in ...

Over the past 20 years, a strange idea called a "weak value" has taken root in quantum information science. Many of the things you can do with quantum technologies entail being able to gain ...

The LHCb collaboration recently reported on the arXiv preprint server the first observation of the decay of the Bc+ meson (composed of two heavy quarks, b and c) into a J/ψ charm-anticharm quark bound ...

Compared to scribbling mathematical expressions for entangled quantum states on a sheet of paper, producing real entanglement is a tricky task. In the lab, physicists can only claim a prepared quantum ...

An international team of researchers at the US Department of Energy's Jefferson Accelerator Laboratory in Virginia has measured the weak charge of the proton for the first time. Although first ...

A new method has been developed allowing for quick and precise measurement of quantum states. At TU Wien, a new method was developed allowing for quick and precise measurement of quantum states.

Scientists at Jefferson Lab in Virginia have precisely measured an important and innate property of the ubiquitous proton for the first time, according to a new paper. The proton property, called its ...

OAK RIDGE, TN—A team of scientists has for the first time measured the elusive weak interaction between protons and neutrons in the nucleus of an atom. They had chosen the simplest nucleus consisting ...

A new result from the Q-weak experiment provides a precision test of the weak force, one of four fundamental forces in nature. The proton's weak charge was found to be QWp=0.0719±0.0045, in excellent ...
