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.

Long-range quantum entanglement is now understood to be a fundamental characteristic of exotic states of quantum matter with an energy gap to all excitations: these include the fractional quantum Hall states found at very high magnetic fields, and certain insulators with possible spin-liquid states. However, such entanglement can also be present in gapless, conducting states of matter (‘metals’ ) found under more ordinary conditions. I will describe recent experiments on the cuprate compounds, and on graphene, which are consistent with the presence of novel metallic states with long-range entanglement.
