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.

Why is it so difficult to build a quantum computer? Quantum theory tells us that nature allows large scale quantum systems to be built and quantum coherently controlled. However we have not found such systems in nature nor built one despite a huge world wide effort over the last decade. In the last few years we have seen the development of small scale quantum information systems emerging. Though such small-scale quantum information systems can in principle run complex quantum computational tasks, the precision of our physical control directly bounds the complexity of possible calculations on these quantum systems. In this talk, we will detail the steps and gaps waiting for us to scale these systems up to large scale fault-tolerant quantum computation.
