One of the oddest predictions of quantum theory – that a system can't change while you're watching it – has been confirmed in an experiment by Cornell physicists. Their work opens the door to a fundamentally new method ...

(Phys.org)—In 1975, Swedish physicist Göran Lindblad developed a theorem that describes the change in entropy that occurs during a quantum measurement. Today, this theorem is a foundational component of quantum information ...
A notable error source in modeling physical systems is parametric uncertainty, where the values of model parameters that characterize the system are not known exactly due to limited data or incomplete knowledge. In this situation, ...

(Phys.org)—It was an interesting week for physics as Popper's experiment was realized again, by a different team this time, using a different approach, causing physicists to wonder what it actually means because the results ...
(Phys.org)—Like Einstein, the philosopher Karl Popper was a realist who was deeply bothered by some of the odd implications of quantum mechanics. Both Popper and Einstein disliked the idea in Heisenberg's uncertainty principle, ...
(Phys.org)—It was a very busy week for physics research. A team of scientists has set a quantum speed limit—the group at the University of California found a way to prove a fundamental relationship between energy and ...
