Atomtronics refers to the process of creating analogues to electronic devices and circuits using atoms. When super-cooled to form Bose-Einstein condensates, atoms placed in an Optical_lattice may form states analogous to electrons in solid-state crystalline media such as semiconductors.An atomtronic battery can be created by maintaining two contacts at different chemical potentials.Analogues of diodes and transistors have also been theoretically demonstrated.

Although atomtronic devices have yet to be realized experimentally, the properties of condensed atoms offers a wide range of possible applications. The use of ultra-cold atoms allows for circuit elements that allow for the coherent flow of information can be used in the future in quantum computers. The use of atomtronics may allow quantum computers that work on macroscopic scales and do not require the technological precision of laser controlled few ion computing methods. Since the atoms are Bose condensed, they have the property of superfluidity and, therefore, have resistance-less current in which no energy is lost or heat dissipated which is similar to superconductivity in electronics.
