In the classical world, the arrow of time defines a clear temporal order among causally connected events. In quantum mechanics, this is not necessarily the case: so-called indefinite causal structures allow for situations in which temporal orders cannot be assigned anymore. What sounds like science-fiction turns out to have serious consequences for a large variety of applications, encompassing communication, computation and cryptography – among many more.
In this Seminar we will introduce the basic notion of indefinite causality and explore how the simplest of such structures unluck phenomena beyond classical physics.
Dr Ebler received Bachelor and Master of Science in Physics from ETH Zurich, and PhD in Physics from The University of Hong Kong. He then served as Senior Research Associate in Quantum Institute of Southern University of Science and Technology and was a long-term Visiting Scholar at the University of Oxford. Presently, Dr Ebler is a Senior Researcher at Huawei Research Hong Kong, leading the Quantum Group. His research interest includes optimization, quantum machine learning, optimization of quantum network architectures, and quantum causality.
