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

Quantum measurement and uncertainty relations lie at the heart of quantum mechanics, delineating fundamental limits on the precision with which non-commuting observables can be simultaneously ...

The demonstration of the first antimatter quantum bit paves the way for substantially improved tests of nature’s fundamental symmetries. Particles such as the antiproton, which has the same mass but ...

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

Scientists have explored how quantum squeezing can improve measurement precision in complex quantum systems, with potential applications in quantum sensing, imaging, and radar technologies. These ...

Quantum physics keeps challenging our intuition. Researchers have shown that joint measurements can be carried out on distant particles, without the need to bring them together. This breakthrough ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

Quantum gravity is the missing link between general relativity and quantum mechanics, the yet-to-be-discovered key to a unified theory capable of explaining both the infinitely large and the ...
