Cold Atoms in a Cryogenic Environment

The book explores two innovative methods for creating cold rubidium atoms in a cryogenic 4K environment. The first method utilizes electron-induced desorption combined with a magneto-optical trap, achieving significantly higher loading rates than traditional dispensers. The second method involves superconducting magnetic transport, successfully moving over a hundred million cold atoms at 50µK into the cryogenic setting. These techniques lay the groundwork for developing a hybrid quantum system that integrates cold atoms with superconducting transmon qubits, facilitating advanced quantum applications.
