Cryogenic Cooling

Cryogenic cooling is the process of cooling using cryogenic agents such as liquid nitrogen, liquid carbon dioxide, or liquid helium. In quantum computing, cryogenic cooling is often used to cool certain qubits, such as superconducting and spin qubits, down to a temperature of a few Kelvin or lower, which is required to ensure they do not lose their quantum state. One of the properties of neutral atoms is that they do not require cryogenic infrastructure. While neutral atom qubits are laser-cooled down to microkelvin temperatures, the machinery required to operate them works at standard room temperature.
