Tomorrow we have two master thesis talks scheduled, from Lennart Baumgärtner and Sami Boulebnane, both related to quantum clocks. Sami will tell us about "Quantum clocks and non-demolition measurement", and as Lennart mentioned in his email on Friday, he'll tell us about "The Information-Content in Clock Signals". 

Apologies for the double booking, but by happy coincidence, they are both on very similar topics. 

Best,
