Quantum Technology Advances with 'Breath' Between Atoms.
Researchers at the University of Washington have discovered that they can detect atomic "breathing" by observing the type of light emitted by atoms when stimulated by a laser. This atomic "breath" could help encode and transmit quantum information. The team also developed a device that could serve as a new type of building block for quantum technologies. The device involves only a small number of atoms and can control multiple emitters and their associated phonon states, enabling quantum emitters to "talk" to each other, a step toward building a solid base for quantum circuitry.
