Quantum Neural Networks - Our brain as a quantum computer?

Presented by Ms. Maria SCHULD on 9 Jul 2014 from 15:20 to 15:40
Type: Oral Presentation
Session: Theoretical
Track: Track G - Theoretical and Computational Physics


Neuroscience and quantum physics have a central feature in common. Both disciplines study objects that largely remain a mystery to scientists. While a century after the discovery of quantum theory, physicists still struggle to interpret their quantum objects' counterintuitive behaviour, biologists are not even close to understanding the mechanisms underlying the remarkable performance of our brain. The research field of Quantum Neural Networks (QNNs) combines both `mysteries' by investigating how established models of neural networks can be formulated in the language of quantum theory. Far away from the rather esoteric discourses of a `quantum brain', QNN models first and foremost aim at developing efficient algorithms to run on future realisations of quantum computers. QNNs thereby promise to provide a substantial speed-up or increased memory capacity relative to classical neural networks. However, beyond questions of powerful computing technology, a success in the yet relatively small field of QNN research could give a first hint that our brain makes use of quantum mechanics to master its incredible tasks. In that sense, QNN research can be seen as a subdiscipline of the `dawn' of quantum biology which evaluates the question of how nature employs quantum effects in macroscopic (i.e. hot and dense) environments to optimise its processes. This presentation intends to give an introduction into Quantum Neural Networks research and to access the question of the potential of our brain to use quantum computing algorithms.
