What is quantum electronics?

In the field of quantum electronics, scientists study the interaction of radiation and mass on a quantum level. Using knowledge from electronics and physics scientists have made many progress in optics and radio physics. Machines such as amplification of light by stimulated radiation emissions (laser) and microwave amplification with stimulated radiation emissions (Maser) are particularly useful in quantum electronics.

The quantum theory is accepted as a basic theory of physics that unifies all physical devices. Any electronic device can be considered a quantum electronic device. However, most scientists understand quantum electronic devices as devices that stimulate transitions between quantum energy. Lasers and Masers are primary devices used in quantum electronics because each of them focuses energy into a tight, focused beam. Transistors and superconductors can use quantum mechanics princesses, but are usually not considered quantum electronic devices.

in KVanty electronics are especially imports between quantum energy. Atoms, molecules and other quantum systems contain excited particles. These systems can only contain a certain, strictly defined amount of energy. When the system releases electromagnetic radiation, in the form of light or radio waves, it moves from a higher level of energy to lower. Lasers and masers can be used to excite these atoms or molecules to higher energy states.

Lasers are one of the main devices used in quantum electronics. These machines emit light waves in focused beam in a narrow range of radiation. This makes the light that the laser emits monochrome, while most light sources emit more light colors, even if the light seems to be only a color for the eye.

Lasers are important in both research and practical problems. Laser light does not work warm and postsHe will give an electric charge. Laser can work in corrosive gases and vacuum. They are useful when measuring the distance with high accuracy, optical communication and thermonuclear fusion.

Another tool that is commonly used in quantum electronics is Maser. These devices emit microwave radiation in focused beam. The frequency of these micrins is stable and does not deteriorate as easily as standard microwaves. The application of this machine allows communication towers that emit the sound waves in the range of microwave radiation and send information over long distances with little distortion.
