Quantum mechanics replaced the clockwork certainty of classical physics with something far stranger: a framework in which particles do not follow single, predictable paths but instead exist as clouds ...

They ask us to believe, for example, that the world we experience is fundamentally divided from the subatomic realm it’s built from. Or that there is a wild proliferation of parallel universes, or ...

Are the mysteries of quantum mechanics finally starting to crack, or are we just getting better at asking sharper questions? Since the 2022 Nobel Prize in Physics honored experiments on quantum ...

Explicit learning goals Interactive lectures Transformed homework problems (including a "bank" of potential HW problems) Common student difficulties & in-class group activities/tutorials Concept tests ...

An international team of researchers have reported 1 new results that they say will have deep implications in understanding "non-locality" issues in quantum mechanics. “Quantum and classical worlds ...

Researchers have developed creative tactics to get rid of loopholes that have long confounded tests of quantum mechanics. With their innovative method, the researchers were able to demonstrate quantum ...

In 1971, graduate student Stuart Freedman and postdoctoral fellow John Clauser took over a room in the sub-basement of Birge Hall at the University of California, Berkeley, and built an experiment ...
