(Phys.org)—Theoretical physicists Robert Alicki and Mark Fannes of the University of Gdansk and the University of Leuven respectively, have uploaded a paper to the preprint server arXiv where they theorize that it should ...
What is light made of: waves or particles? This basic question has fascinated physicists since the early days of science. Quantum mechanics predicts that photons, particles of light, are both particles and waves simultaneously. ...

(Phys.org)—As understood in the field of quantum mechanics, objects are able to exist in more than one state at a time, a property known as superposition. Measuring such states is a challenge however, as doing so causes ...
A deeply rooted concept in everyday life is causality; the idea that events in the present are caused by events in the past and, in turn, act as causes for what happens in the future. Physicists from the University of Vienna ...

Werner Heisenberg's uncertainty principle, formulated by the theoretical physicist in 1927, is one of the cornerstones of quantum mechanics. In its most familiar form, it says that it is impossible to measure anything without ...

(Phys.org) -- With all the talk of quantum computers, little notice has been made of work on what is known as a quantum Internet, which is where data is sent across a web of computers via devices that work at the quantum, ...
An international collaboration led by physicists of the University of Vienna shines new light on the question of the resources required for achieving quantum information processing. The scientists demonstrate that less demanding ...
