Broadband sympathetic electromagnetically-induced transparency (EIT) cooling

An apparatus comprising at least one processor and memory storing computer-executable instructions, the computer-executable instructions configured to, when executed by the at least one processor, cause the apparatus to at least:

• control a first manipulation source to provide a first manipulation signal to a particular region of an atomic object confinement apparatus;
• and
• control a second manipulation source to provide a second manipulation signal to the particular region of the atomic object confinement apparatus,
• wherein:
• an atomic object is located within the particular region of the atomic object confinement apparatus,
• the first manipulation signal and the second manipulation signal are configured to collectively cool the atomic object,
• the first manipulation signal is characterized by a first wavelength corresponding to a transition between an S manifold and a P manifold of a first component of the atomic object and detuned from the transition between the S manifold and the P manifold by a first detuning,
• the second manipulation signal is characterized by a second wavelength corresponding to a transition between the P manifold and a D manifold of the first component of the atomic object and detuned from the transition between P manifold and the D manifold by a second detuning, and
• the first detuning and the second detuning are selected to establish a dark state associated with a two photon transition between the S manifold and the D manifold.
