In the double slit experiment, a particle travels on two different paths at the same time. Something similar can be observed when a helium atom is ionized with a laser beam. The ionization of helium can happen via two different ...

In 1937, US physicist Isidor Rabi introduced a simple model to describe how atoms emit and absorb particles of light. Until now, this model had still not been completely explained. In a recent paper, physicists have for the ...

So far it exists mainly in theory, but if invented, the large-scale quantum computer would change computing forever. Rather than the classical data-encoding method using binary digits, a quantum computer would process information ...
