Here are the details for the next Q+ hangout.
Date: 25th September 2012
Time: 10am British Summer Time
Speaker: Stephanie Wehner (Singapore)
Title: Uncertainty and the generation of randomness
Abstract: We consider the creation of classical randomness by making measurements on a largely unknown quantum system. We show a close relations between measurements that are good at this task and measurements that satisfy strong uncertainty relations. Finally, we mention an application to quantum cryptography.
Please note the unusual start time.

Just noticed that the database does not contain any mention of Stephanie Wehner…Is this like an surprise hangout? Or did the speaker confirmed on the go?
What do you mean by the database?
