How the Third Law Limits our Knowledge about Quantum Systems
July 9th, 2019 MARCUS HUBER IQOQI Vienna

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.
