Quantum electronics is a loosely defined field encompassing interactions between electromagnetic radiation and matter at the atomic level involving quantum levels and resonance phenomena. The field of quantum electronics includes lasers, masers, and their scientific applications. Although the mechanism by which solid-state electronic devices, such as transistors, operate is also quantum-mechanical in nature, these devices are not usually included in the field of quantum electronics.
