Atomic Vapor Cell
Heart of Quantum Device
Atomic vapor cell is a core component of quantum device such as atomic gyroscope, atomic magnetometer or atomic clock. It is also known as atomic cell, atomic chamber, gas cell, gas chamber, rubidium bubble, cesium bubble, iodine bubble, glass cell, glass chamber, resonance cell, atom cell, atom chamber, atomic reference cell, microfabricated cell, and so on.
