Towards topological quantum computing in the brain — •Chrsitian Kerskens — Institute of Neuroscience, Trinity College Dublin

In recent years, the mathematical formalism of quantum theory has been adopted to formalise models of cognition. However, the success of quantum cognition over classical approaches opens up the following questions; Is the computing power of the brain sufficient to simulate quantum computation? And if yes, why would nature use so much computational power to simulate quantum computing resulting in a low reliability through non-commutative behaviour and human error? We believe that the brain doesn't simulate quantum computing. Instead, we propose that consciousness and cognition is based on topological quantum computing (TQC), which may be, if at all, the only way of quantum computing reliable enough in the wet and hot environment of the brain . The proposal relies on the experimental findings that the two main ingredients to realise TQC, topological defects and topological phase, may exist in the conscious brain. While the existence and important roles of topological defects are well established, we will focus on questions around the topological phase. Especially, we will discuss why our recent results which showed long-range quantum entanglement in the conscious brain can be interpreted as a topological phase. Further, we will discuss how the experimental results can shed light on the underlying mechanisms which provide the topological-like phase.
