A single atom, by its nature, can only emit one photon at a time. A single photon can be generated at will by applying a laser pulse to a trapped atom. By putting a single atom between two highly ...

A single rubidium atom is trapped in an optical resonator consisting of two highly reflective mirrors. Repeated excitation of the atom causes several entangled single photons to be emitted in ...

The clock uses a rubidium vapor lamp and a glass cell containing rubidium. A voltage-controlled oscillator excites the cell with a 6.8 GHz signal. Rubidium atoms can exist in three states.

Once cooled, a series of three laser flashes are shone on the atoms, creating matter waves in the rubidium atoms. According to the laws of quantum mechanics, at extremely low temperatures, atoms ...

In its announcement, Airbus said that the plan was to build an engineering model of an accelerometer based on rubidium atom interferometry. “Benefitting from the heritage of its research institutions, ...
