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.

Topological Quantum Matter and Entanglement. Lise Meitner Distinguished Lecture NOTE THE NEW DATE
FR4 (Kleinsalen) ()
Long-range "entanglement" was initially pointed out by Einstein as a strange property
predicted by quantum mechanics that he felt was so contrary to common-sense that
experiments to test it would surely undermine the quantum theory. But when experimental tests eventually became possible, quantum mechanics was vindicated. In recent years, it has been realized that, instead of merely being an abstract and obscure philosophical issue in the interpretation of the quantum theory, entanglement is in fact perhaps its central feature, and in particular, plays an important role in the new "topological (quantum) states of matter" which have unexpected properties that have given rise to much recent excitement in condensed matter physics. I will describe some examples of this and how ideas from quantum information theory and condensed matter physics have fruitfully joined together.
