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.

I will begin by recalling how I met the late Nikola Buric and how our friendship developed in a short time. Motivated by quite different interests in the transition between quantum and classical mechanics, at first, we both were studying possibilities for a theory of quantum-classical hybrid systems, which became the focus of our discussions. - This has recently led me to explore cellular automata (CA) which, quite surprisingly, show well known features of quantum mechanics (QM). Such as a linear updating rule resembling a discretized form of the Schroedinger equation together with its conservation laws. In particular, a whole class of natural Hamiltonian CA, which are based entirely on integer-valued variables and couplings and derived from an action principle, can be mapped reversibly to continuum models with the help of sampling theory [Shannon's Theorem]. This results in "deformed" quantum mechanical models with a finite discreteness scale l, which for l-> 0 reproduce the familiar continuum limit. Such CA can form multipartite systems consistently with the tensor product structures of many-body QM, while maintaining linearity. Interestingly, discreteness necessitates a many-time formulation reminding of relativistic dynamics. We conclude that the superposition principle is fully operative already on the level of such primordial discrete deterministic automata, including the essential quantum effects of interference and entanglement and might offer a primitive understanding of the Born rule. - Time permitting, I will relate these findings to the Cellular Automaton Interptetation of QM, recently proposed by G. 't Hooft.
