Quantum Simplicity: Introduction to Complexity Science in a Quantum World

A masterclass with Assistant Professor Mile Gu, Nanyang Assistant Professor, Nanyang Technological University and UWA Institute of Advanced Studies Visiting Fellow.

Complexity and quantum science appear at first to be two fields that bear little relation. One deals with the science of the very large – seeking the understand how unexpected phenomena can emerge in vast systems consisting of many interacting components. Quantum theory, on the other hand, deals with particles at the microscopic level and is usually considered limited to the domain of individual photons and atoms. Yet, different as they appear, there is growing evidence that in interfacing ideas from quantum and complexity science, we may unveil new perspective in either both fields.In this masterclass, Mile Gu will first give a tutorial on computational mechanics, a branch of complexity science captures structure by building the simplest causal models of natural observations. He wll then illustrate how many processes that require complex classical models may be simulated by remarkably simple quantum devices and describe recent experiments to test this laboratory conditions.  He will survey the potential consequences these developments, highlighting how the indicate that fundamental notions of structure, complexity, and even the arrow of time, may change when the quantum properties of information are taken account. He will then review recent experiments in, where many of these consequences are illustrated through photonic systems.

Mile Gu currently leads the quantum and complexity science initiative - which seeks to explore how quantum technologies can help us understand the science of complex systems ( and holds appointments with the Complexity Institute at Nanyang Technological University and the Centre for Quantum Technologies at the National University of Singapore. Gu’s past research span the areas of quantum information, complexity theory and optical quantum computation, and has been featured in Science and Natural suite Journals. Prior to his current appointment, Gu obtained his PhD at the University of Queensland, and spent three years as faculty at the Institute for Interdisciplinary Information Sciences Tsinghua University under the China 1000 talents program.
