Workshop »Interplay of quantum information, foundations and gravity« Mitschnitt einer Veranstaltung des Institute for Quantum Optics and Quantum Information (IQOQI) am Mittwoch, dem 30. Mai 2018 im Theatersaal der Österreichischen Akademie der Wissenschaften Teil 14: Daniel Grumiller: Quantum null energy condition - a remarkable inequality Kamera und Schnitt: Daniel Winkler Daniel Grumiller ist Professor am Institut für Theoretische Physik der Technischen Universität Wien. Abstract: Inequalities are ubiquitous in mathematics and physics. Among the interesting ones are so-called energy conditions, since they seem plausible (energy is positive) and are useful (e.g. for proving singularity theorems). However, all local energy conditions are violated by quantum effects, so an intriguing question is whether or not there is some local quantum energy condition. Bousso et al. recently proposed the Quantum Null Energy Condition (QNEC), conjectured to hold universally. I review basic features and holographic as well as quantum information aspects of QNEC.
