Abstract:
The third law of thermodynamics can be phrased as an impossibility of cooling any physical system to absolute zero temperature. The projection postulate of quantum mechanics, however, predicts pure post-measurement states in idealised settings. We show how a self-contained treatment connects the two concepts and extends the impossibility of cooling to the impossibility of perfect measurements or Landauer erasure with finite thermodynamic resources.

Biography:
Marcus Huber is a group leader at IQOQI in Vienna. He has received his PhD from University of Vienna.
After, he has been a Marie-Curie Fellow at the University of Bristol, and held positions of the Universities of Geneva and the Universitat Autonoma di Barcelona.
