Physicists have pushed one of the strangest ideas in science into new territory, holding tiny clumps of metal in a quantum limbo that recalls Schrödinger’s famous cat. Instead of a single atom or ...

A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

When the six tiny spacecraft of NASA's SunRISE (Sun Radio Interferometer Space Experiment) mission settle into their orbits ...

Physicists in Israel have created a quantum interferometer on an atom chip. This device can be used to explore the fundamentals of quantum theory by studying the interference pattern between two beams ...

Add Yahoo as a preferred source to see more of our stories on Google. In 1920, Danish physicist Niels Bohr proposed that although light (photons) has a dual nature, behaving as both particle and wave, ...

Dark energy — a mysterious force pushing the universe apart at an ever-increasing rate — was discovered 26 years ago, and ever since, scientists have been searching for a new and exotic particle ...

Measurement-based linear optics implements a huge multi-mode interferometer consisting of beamsplitters (green) and phase delays (blue). The size of the virtual interferometer can be many hundreds or ...
