156. Lecture: Quantum entanglement and black holes

Quantum entanglement plays an important role in two seemingly distinct areas of physics: For studying the quantum properties of black holes as well as for quantum information theory. Quantum entanglement and computational complexity may be mapped to geometric quantities. This provides a new link between theoretical concepts for black holes and quantum information. A central role in this...

157. Experimental Simultaneous Extraction of Non-Commuting Obervables for Accessing Quantum Correlations in a Spinor Bose-Einstein Condensate

While entanglement between single pairs of discrete entities like photons, atoms, or ions is routinely implemented and investigated in experiments, the extension to continuous systems is still a challenge on the side of preparation as well as detection. We explore this continuous limit with our experiments employing a quasi-1-dimensional Bose-Einstein condensate of ^{87}Rb which features rich...

158. Programmable Interactions and Emergent Geometries in an Atomic Array

Philipp Kunkel (Stanford University)

Interactions form the basis for the experimental generation of entanglement between quantum objects. Typical quantum simulation platforms such as atomic systems or trapped ions feature local interactions which decay as a function of distance. The spatial entanglement structure that can be generated is thus inherently connected to the physical geometry of the system. In this talk, I will...
