absolute zero

The chip, cocooned within a vacuum chamber and cooled nearly to absolute zero, is patterned with 198 gold electrodes, arranged like an oval racetrack.

Researchers from TU Delft and Brown University have engineered string-like resonators capable of vibrating longer at ambient temperature than any previously known solid-state object -- approaching what is currently only achievable near absolute zero temperatures.

After cooling the nodes to close to absolute zero, light is sent through the first node and, by nature of the silicon vacancy center's atomic structure, becomes entangled with it.

To manipulate and arrange atoms, physicists typically first cool a cloud of atoms to temperatures approaching absolute zero, then use a system of laser beams to corral the atoms into an optical trap.

The temperature of these atoms is approximately -273 °C -- very near absolute zero -- and there are two mirrors with a light field in between them to enhance the atomic interactions.
