In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

Interfacing a single trapped atom to a pair of indistinguishable photons
(ICFO, The Institute of Photonic Sciences)
We describe a system to interact tunable, atom-resonant single photons from cavity enhanced spontaneous parametric down conversion with individual atoms trapped at the focus of four high numerical aperture lenses. The setup is novel and versatile, as it allows us to trap one or more atoms in the same potential or in an array of traps by means of a standing wave, and, interestingly, it allows us to probe the system and collect scattered light with a large solid angle, and from two orthogonal directions with respect to the trapping beam. Promising applications of the study of isolated quantum systems can be found in quantum information science, e.g. for investigating quantum interference between atoms, or quantum simulation with arrays of Rydberg atoms. By combining resonant photon pairs with single atoms, we aim at studying fundamental light-matter processes that to date have never been directly studied, such as the stimulated emission from a single photon, single and two-photon interference using a single atom as a beam splitter.
