A test performed on antihydrogen atoms has shown that gravity acts on matter and antimatter in a similar way. The experimental feat is the latest in efforts to probe the crossover between theories of ...

A quantum property associated with tiny objects has been found to persist in an experiment with more than a thousand atoms. This could help us understand where the boundary between the quantum world ...

Physicists 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 of atoms.
