Hi all,

***Note: we'll start a little bit later than usual --- 14:00 instead of 13:45*** This week Anian Altherr will present the results of his semester project, entitled "Quantum Stop Watches". The abstract is below.

Best,

Title: Quantum Stop Watches Abstract: Clocks can be used to build stop watches. We show under some fair assumptions that if a clock ticks sufficiently accurately, the stop watch built with this clock can be used to estimate time accurately, too. Furthermore, we provide some evidence that a stop watch can be built using an optimal quantum clock, the Quasi-Ideal clock, which outperforms classical clocks.
