    Interacting emitters are the fundamental building blocks of quantum optics and quantum information devices. Pairs of organic molecules embedded in a crystal can become permanently strongly interacting when they are pumped with intense laser light.

    The scalability of quantum information processing applications is generally hindered by loss and inefficient preparation and detection. A minimal loss network based on phonons has now been realized with trapped ions.

    Whether or not an electron wavepacket accumulates a time delay when tunnelling out of an atom is still under debate. Improved all-optical characterization of the tunnelling dynamics by combining one- and two-colour driving fields may shed light on this question.

    Bringing next-generation atomic clocks out of the lab is not an easy task, but doing so will unlock many new possibilities. As a crucial first step, a portable atomic clock has now been deployed for relativistic geodesy measurements in the Alps.

    Light propagating through a cloud of cold atoms can be slowed down by exciting a certain type of spin wave in the atomic ensemble. This stationary light could find applications in quantum technologies.

    Coupling the fluorescence of cold atoms to plasmons propagating on a gold surface offers a means of controlling the radiation from optical emitters without the need for a cavity.

    A quantum memory that combines high-efficiency and long lifetime is now demonstrated. Employing a collective excitation, or spin wave, in an ensemble of atoms in a trap improves memory lifetime, while incorporating the trap into an optical ring cavity simultaneously aids higher retrieval efficiency.
